problem coding odd loop

shams · 07-16-2004, 08:12 PM

hi,
it is suppose to be an odd loop but it is terminating after the first output,plz tell me where is
the mistake:
include <stdio.h>
main()
{
char another='y';
int num;

while(another=='y')
{
printf("Enter a number\n");
scanf("%d",&num);
printf("square of %d is %d\n",num,num*num);
printf("\nWant to enter another number y/n\n");
scanf("%c",&another);

}

You are missing a right brace. I'm suprised this compiled at all.

include <stdio.h>
main()
{
char another='y';
int num;

while(another=='y')
{
printf("Enter a number\n");
scanf("%d",&num);
printf("square of %d is %d\n",num,num*num);
printf("\nWant to enter another number y/n\n");
scanf("%c",&another);

}

}/* missing brace here*/

Hi shams,

Try putting a space before the %c. Make the scanf line:

Code:

scanf(" %c",&another);

scanf() leaves the \n (from the ENTER key) on the input butter. After each scanf() try adding a getchar(); to get rid of it.
