Question

c语言,输入4个学生的语数外成绩,计算出每个人的总分,每门课的平均分?

Answer 1

#include <stdio.h>
int main() {
double mark[4][3], aver[4], high[3] = {0};
int i, j;
for (i = 0; i < 4; i++) {
double all = 0.0;
printf ("请输入%c的三门成绩：\n", 'A'+i);
for (j = 0; j < 3; j++) {
scanf ("%lf", &mark[i][j]);
high[j] = high[j] < mark[i][j] ? mark[i][j] : high[j];
all += mark[i][j];
}
printf ("%c同学的总成绩是：%.2lf\n", 'A'+i, all );
printf ("%c同学的平均成绩是：%.2lf\n", 'A'+i, all / 3);
}
}
