What is the output of this program?
#include <stdio.h>
struct
{
int i;
float ft;
}decl;
int main(){
decl.i = 4;
decl.ft = 7.96623;
printf("%d %.2f", decl.i, decl.ft);
return 0;
}
Answer: A
Correct answer: 4 7.97
%.2f prints the float rounded to two decimal places, so 7.96623 comes out as 7.97. The rounding is in the output only - the stored value is unchanged. The structure has no tag, but that is legal because the variable decl is declared with it.
