C语言for循环和数组的使用

// scores_in.c -- uses loops for array processing
#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]);  // read in the ten scores
    printf("The scores read in are as follows:\n");
    for (index = 0; index < SIZE; index++)
        printf("%5d", score[index]); // verify input
    printf("\n");
    for (index = 0; index < SIZE; index++)
        sum += score[index];         // add them up
    average = (float) sum / SIZE;    // time-honored method
    printf("Sum of scores = %d, average = %.2f\n", sum, average);
    printf("That's a handicap of %.0f.\n", average - PAR);

    return 0;
