After showing this to him, he said i should use Lazarus to create the application with GUI and use A menu that can allow me choose to input a string and then encrypt it. I have tried it on Lazarus but failed and i dint understand the menu. please i need help, Its a assignment.

]]>I can create TMenuBar and MenuItems under Linux at compile time.

But I am lost, when I try to create/add/modify it at runtime.

How can I do this?

Tanks for helping hands

I have a Pascal source file which I need to compile, you can find code like this in it:

```
type x = array [1:2] of integer;
a = ^b;
b = record u: x;
v : pointer;
w,o : a;
end;
```

The file doesn't compile with fpc, what kind of dialect of Pascal may it be?

Thanks for your help!

I'm using the Lazarus IDE v1.2.6 pascal environment on Windows8 and it's working great. I'm able to use my original code and add some nicer string processing functions with the SysUtils extension. I'm pretty certain there's no way to integrate images into the default text display window where the program actually displays it's text...but I'm hoping there's a way to have my code integrate the popup of a graphic friendly window with each new at-bat displaying an image of the pitcher and hitter.

What I'm really hoping to find is a very simple example of some code that accomplishes this...I work much more effectively finding a simple code fragment that I can further modify for my specifics.

Thanks!

Dennis

I'm just learning to code so I might come across as not the brightest bubble but you need to start somewhere to eventually get good at it. So, I have free pascal complier for linux (CentOS if that matters). I've been trying to create some graphic but my program wouldn't compile as 'graph' unit(library) is not being recognized. I've had a look in specification and clearly as the sun it is described therefore there must be one included in a standard compiler (or is it not, and if not how do I check that?).

Thanks for help (any will be really welcomed).

]]>As I mentioned in a different thread I am just starting off with programming. I choose Pascal mainly because it's the first language you are being thought at uni (at least where I live) and secondly in order to overcome my deep, deep aversion to this programming language (long story). The thing I want to ask is - why there are so many versions (apart of obvious, that is - different platforms) and why so many differences. It's really confusing and makes it that much harder to learn when you try something out just to discover that on your version of compiler it just won't work. That is really frustrating. How can I get my head around the problem? Where do I begin?

]]>a tertiary student will be able to receive an educational grant to assist with their tuition and other

expenses. The system should accept specific data on a student and his/her financial situation and then

determine if the student will be able to receive the grant, and how much grant aid will be provided. The

development of the system is to be done on a phased basis with specific requirements for each phase.

Part 1 of the project required you to simulate the processing for a single student to demonstrate your

understanding of the sequence and selection control structures. The requirements for Part 2 are below,

which requires you to demonstrate your understanding of the iteration control structure. Part 2 should

be considered as additional requirements to those which existed for Part 1. In one or two instances, you

may be asked to replace a specific requirement from the previous deliverable with an updated one ¡V

these will be specified.

The management of Universal Ltd. requires the IPO Chart, Pseudocode, Flowchart, Trace Table, and

Pascal code (including sample screenshots of the executable program) for the product as described

below. It will simulate the processing to be done for more than one student. In addition to the

requirements already provided in Part 1, please accomplish the following:

o The program should allow the user to enter any number of student applications. A value

of either XXX (or its lowercase equivalent) for the student name will indicate that no

more records are to be processed. (Note: do not use arrays).

o Previously UL required the program to accept the student¡¦s identification (ID) number.

Given that UL allows for students from various institutions to submit grant applications,

the possibility exists that a student¡¦s ID number could be duplicated in the program. In

anticipation of the processing of multiple students, UL has decided to create its own

unique way of identifying the students, as shown in the example below:

UL1000 ¡V Micky McKenzie

UL1001 ¡V Cherry Blossom

UL1002 ¡V Jamie Jamison

Rather than accept the students¡¦ ID number, you are required to automatically assign a

sequential ID number to a student¡¦s application (as in the example above). This now

becomes the application number. All other inputs, as outlined in Part 1, remain the

same.

2

o UL wants you to ensure that error-checking is done for all inputs of financial data. Recall that a zero value may be entered in the event a particular cost does not apply.

o Instead of the output requirements outlined in Part 1, UL now wants you to display for each valid application:

„X Application number

„X Student Name

„X Total Educational Expenses

„X Amount Paid

„X Shortfall

„X Application Status

o UL would like a menu-driven statistical summary of the information received from the processing of the applications. As soon as the information has been entered for all students, display the menu shown below and prompt the user to enter an option.

A. Ratio of Total Amount Paid to Total Educational Expenses

B. Ratio of Applications Being Considered for Grants to Applications Processed

C. Average Grant Amount Required per Eligible Student

X. Exit

The program should determine the results to display based on the respective menu options. After displaying the information to the user, the system should continue to re-display the menu to allow the user to make another choice until the user selects the option to exit. Thereafter, the program should terminate.

Make a program in Pascal that after has read a text with a list of nums., it will return the numb. of the nums that appear less than one times in the text.

The text that will be read from the program should be like that.

In the first line there are two nums. seperated by a space, n and m. N is the number of nums that exist, like if the text contains the numbers 1,2,3,4, n is 4 (1..n).

M is how many lines follow.

Every line has a couple of nums, a,b, (1=<a=<n), (1=<b=<n) (a<>b)

a and b are separated by a space.

The file that the program will make will have written on it a num., that says how many nyms are appeared less than two tims in the text.

All the nums. are Integer.

0=<p=<n

i've made the following program, but it only reads the first line of the text. Anyone that can help me? The deadline is almost ended. Thanks in advance.

My code is the following.

Program thefinalp;

Uses SysUtils;

Var

f:Text;

m,d:Integer;

n:Char;

c:String[1];

a,e:array of integer;

LowArr:Integer;

HighArr:Integer;

ArrayLen:Integer;

i:Integer;

begin

Assign(f,'finalp.txt');

Reset(f);

repeat

Read (f,n);

Write(n);

until (n=' ');

Read(f,c);

Write(c);

while not SeekEoln(f) do

begin

read(f,d);

Write(d);

End;

Readln;

Writeln;

StrToIntDef(n,m);

setlength(a,m);

LowArr:=Low(a);

HighArr:=High(a);

ArrayLen:=Length(a);

setlength(e,m);

LowArr:=Low(e);

HighArr:=High(e);

ArrayLen:=Length(e);

for i:= LowArr to HighArr do

begin

repeat

Read (f,a[i]);

Write(a[i]);

until (n=' ');

Read(f,c);

Write(c);

while not SeekEoln(f) do

begin

read(f,e[i]);

Write(e[i]);

End;

Readln;

Writeln;

End;

Readln;

End.

I've made the code after that, the program is how to put into variables all the nums.

I'm a beginner so if anyone could give me an example, would help a lot.

The file represents stock as it is purchased. Therefore more products may be added to it of different/same sizes and barcodes. Each individual item creates a new record whether it be a new size or barcode for example if you have two products of the same barcode and size it stores them as two records. I need a procedure which sorts the records into ascending order of the barcodes and combines the sizes to one record and marks the others for deletion so that the file is like the one in the image below:

http://postimg.org/image/y8sk6dg1p/

-1 means its marked for deletion

i was told i need to do a nested while loop. However i was unable to get it to work

Recently I was thinking of how useful a prime number finder would be. And Im pretty sure there are millions out there, but I tried to build my own.

. After some struggle (and perhaps, as you'll see, some redundancies) I've came up with my own design. You enter the lower and upper values and the program will give you all the primes between both values. Problem is, it stops after "finding" the number 61. No matter what range I use! Could you please help me out?

The task is to put given number of knights, on given size chess board, that every square of the board is covered. That is, every square on the board is either occupied by a knight or attacked by a knight. knights can attack each other. the solutions are givven here. [link=http://www.contestcen.com/knight.htm][/link]

i am using recursion. algorithm:

1. choose not occupied square

2. try every knight, which can occupy that square

3. choose another square and so on, till knight max number is reached.

basicly, i try every posibble knight positions.

i wrote program, which is below, but it crashes when i put more than 6 knights, and show nonsense in boards below 6. i know that the problem is in backtracking, when i need to delete a knight. but i dont know how to correct it.

again, praying for your help. Thanks in advance.
