Thread: This one is so annoying(Problem with my while loop)

Hi.I am stuck on this question for a week .i need alil help from you guys....

This question is taken from the book ( C How to program 3/e by Deitel & Deitel) from the chapter 3 , question 3.38.

3.38 Write a program that prints 100 asterisks, one at a time. After every tenth asterisk, your program should print a newline character. (Hint: Count from 1 to 100. Use the modulus operator to recognize each time the counter reaches a multiple of 10.)

Above is the question .To make the question more clear hear is what the output should be for the program.

Above is the output for the program .Below is the code i wrote for this Question.

#include <stdio.h>

int main()
{
int cnt;
cnt =0;
clrscr();

while ( ++cnt <= 100 ){
printf ("*");
if ( cnt == 10 )
printf ("\n");
cnt = 0
}

return 0;
}

My programm is giving me an infinite loop.

Thanks alot

Look at your code:

int main()
{
int cnt;
cnt =0;
clrscr();

while ( ++cnt <= 100 ){
printf ("*");
if ( cnt == 10 )
printf ("\n");
cnt = 0
}

return 0;
}


You are resetting cnt to 0 everytime that it reaches 10 - therefore it will never reach 100 to break out..

Look at how to use the modulus operator....

Thanks alot ..

well the printf statement is a bit new to me

help me out

printf ( "%c", ( i % 10 ) ? '*' : '\n' );
