Answer 1

定义一个5个元素的数组，统计各分数段人数就行

#include <stdio.h>
int main()
{
    int score[10] = {90,85,82,57,69,88,98,62,47,75};
    int grade[5] = {0};
    int i=0;
    printf("输出原始成绩:\n");
    for(i=0;i<10;i++)
        printf("%4d",score[i]);
    printf("\n输出统计结果:\n");
    printf("%-10s%-10s%-10s%-10s%-10s\n","0~59","60~69","70~79","80~89","90~100");
    for(i=0;i<10;i++)
    {
        if(score[i] >= 90)
            grade[4]++;
        else if(score[i]>=80)
            grade[3]++;
        else if(score[i]>=70)
            grade[2]++;
        else if(score[i]>=60)
            grade[1]++;
        else
            grade[0]++;
    }
    for(i=0;i<5;i++)
        printf("%2d人%6s",grade[i]," ");
}
