Note, TUHS probably isn't the *best* forum to ask for help with basic C
programs. :-)
That said, I suspect you mis-transcribed the program and that the line,
`sum = sum + 1;` should be `sum = sum + i;`, or more idiomatically, `sum +=
i;`. Indeed, the whole program could be written:
#include <stdio.h>
int
main(void)
{
int i, sum = 0;
for (i = 1; i <= 100; i++)
sum += i;
printf("%d\n", sum);
return 0;
}
If you're using a C99 or later compiler, you can be slightly more succinct:
#include <stdio.h>
int
main(void)
{
int sum = 0;
for (int i = 1; i <= 100; i++)
sum += i;
printf("%d\n", sum);
return 0;
}
Hope that helps!

Hello everyone
I had a problem compiling a piece of c code from the book. The result of
running the book is 5050, but the compiler is 100. I don't know which is
right, please help me to see which is wrong. Thank you very much!
#include <stdio.h>
int main(void)
{
int i, sum = 0;
i = 1;
while ( i <= 100) {
sum = sum + 1;
i++;
}
printf("%d\n", sum)
return 0;
}
