Its not necessary that every time you will give the same set of numbers as input i.e, {1,2,88,42,99) . It may differ, that set no.shown in problem is only an example to make u understand.

You must declare i in the first of program not in the body of for loop it will be like this.hope it help

int main(void) {

int i; //here is the change declare it must be here
int value[] = {1, 2, 88, 42, 99};

for ( i=0; i<3; i++) {

 printf ("\n%d\n", value[i]);

   }

return 0;
}
