1. Write a program to copy its input to its output, replacing each string of one or more blanks by a single blank.

Hi.
First of all, i would like you to know that if you are receiving strings in c console applications, it doesn't receive blank spaces (i use dev c++). But what you wish to do is possible. The steps you will need are;

a. Receive string as input.
b. Convert the string to a character array.
c. Using a loop test if each array element is a space.
d. Use a variable to indicate when the array element is a space. (a Boolean variable best suites this. It should be set to false if a space is not found and set to true if a space is found)
e. If the Boolean variable is true, then don't modify your output.
f. If the Boolean variable is false, then modify your output.

I wrote the code below to show you what i mean;


#include
#include
#include



int main()
{
int myint = 0; //integer variable used to indicate the presence of a space
int i = 0; //integer variable used to move through the array
int count = 0; // integer variable used for updating the output array
char mystring[12]; //Input string
char myoutput[12]; //Output String

//Setting out input string to: qwe t t y
//Notice it has 3 consecutive spaces, then one space then two consecutive spaces
mystring[0] = 'q';
mystring[1] = 'w';
mystring[2] = 'e';
mystring[3] = ' ';
mystring[4] = ' ';
mystring[5] = ' ';
mystring[6] = 't';
mystring[7] = ' ';
mystring[8] = 't';
mystring[9] = 't';
mystring[10] = ' ';
mystring[11] = 't';

for ( i = 0; i <= 11; i++)
{
if ( mystring[i] == ' ' ) // If the input string finds a blank space
{
if (myint == 0) //If our indicator variable if 0 meaning previous was not a blank space
{
myint = 1; //Change indicator variable to 1 meaning a blank space found
myoutput[count] = mystring[i]; //Update output
count ++ ; // increase count to move to next space in output array
}
}

else if (mystring[i] != ' ') // if our input string doesn't find a blank space
{
myint = 0; //Change indicator variable to 0 meaning a blank space not found
myoutput[count] = mystring[i]; //Update output
count ++; // increase count to move to next space in output array
}
}

// Printing of input and output to display the difference
printf("Old String: ");
printf("%s", mystring);
printf("
");
printf("New String: ");
printf("%s", myoutput);
printf("
");
system("pause");
}
