如何控制循环体中的某一个语句仅仅在第一次执行循环时执行一次呢？

Question

如何控制循环体中的某一条语句在多次循环中只执行一次呢？
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#define SIZE 10
#define PAR 72
int main(void)
{
int index, score[SIZE];
int sum = 0;
float average;

printf("Enter %d golf scores:\n", SIZE);
for (index = 0; index < SIZE; index++) {
    scanf("%d", &score[index]);
    printf("%5d\n", score[index]);
    sum += score[index];
}
    
average = (float)sum / SIZE;
printf("Sum of scores=%d,average=%.2f\n", sum, average);
printf("That's a handicap of %.0f.\n", average - PAR);

return 0;

}
例如我想在for循环中控制printf("The scores read in are as follows:\n")这条语句仅仅在第一次执行循环时打印。

Answer 1

if(index==0) printf("The scores read in are as follows:\n")
