Function problems......

SelatosSelatos Member Posts: 5
Ok, I am working with making my own custom functions, and I am trying to follow everything I know about programming, but my books provide so liitle support about this.....

Here's my code:
#include
#include
#include
#include
#include
#include
#include
#include

int getMonsterNumber(int cur_level) {
int monster = random(cur_level);
return monster;
}

main() {
randomize();

int level;
int monsterID;

printf ("Input a level less than 10: ");
scanf ("%d
", level);

monsterID = getMonsterNumber(level);

printf ("Your monsterID could be: %d
", monsterID);
delay(1000);
}


Even though I have a bunch of unnessecary includes, that is for later on, when I will need them, and probably add more to that list.

    Sorry I didn't say, had to post in a hurry :) I want to use the function getMonsterNumber to generate a random monster ID between 0 and the user's current level. It just screws up everytime I run it, ie it wont accept inputs, it just disregards all of my keystrokes until I type in 'exit', its not even giving me a warning/error. Am I using functions wrong?

    ok, it works now, just doesnt return the value correctly. Random generates a number, and then it returns a huge number near '12345'.

    I'm not familiar with the random() call but iostream also has a rand() function which can be scaled using the modulus operator - %. For example, if you wish to limit your return values try using

    returnValue = 1 + rand() % 10; // add 1 because modulus returns 0-9

    according to the value you placed in your last message '12345'... the above line of code would cause returnValue to equal 6 (1+5)

    the only draw back to using rand() that I am aware of is that while it will appear to generate random numbers, its actually generating psuedo-random numbers. This means that the same sequence of results will be produced everytime you run the program. To prevent this you can 'seed' the srand(time(0)); where time(0) is the seed and is based on the PC's clock and for this you will need to include ctime. Hope this helps.

    The interesting part is that when I printf monster, it shows a number between 0 and level, but when I return it, and printf after returning to main, it makes up 12803, to be specific. I havent found anything in my books about this either.....
