c语言中利用三维数组计算成绩总分数
1、
#include <stdio.h>
int main(void)
{
int a[2][4][3] ={{{20,10,12},{30,20,10},{20,10,50},{20,10,30}},{{30,10,20},{40,30,10},{10,20,30},{50,10,20}}};
int sum[4][3] = {0};
int i, j, k;
for (i = 0; i < 4; i++)
{
for (j = 0; j < 3; j++)
{
for (k = 0; k < 2; k++)
{
sum[i][j] += a[k][i][j];
}
}
}
for (i = 0; i < 4; i++)
{
for (j = 0; j < 3; j++)
{
printf("%d ", sum[i][j]);
}
putchar('\n');
}
return 0;
}
