第二次实验第五题。使用二维数组输出表格

#include<iostream>

using namespace std;

void main()

{
int i, j;
float a[4][6];
a[3][5] = 0;
cout << "输入成绩:\n";
for (i = 0; i < 3; i++)
for (j = 0; j < 5; j++)
cin >> a[i][j];
for (i = 0; i < 3; i++)
{
a[i][5] = 0;
for (j = 0; j < 5; j++)
{
a[i][5] += a[i][j];
}
a[i][5] = a[i][5] / 5;
}
for (j = 0; j < 5; j++)
{
a[3][j] = 0;
for (i = 0; i < 3; i++)
{
a[3][j] += a[i][j];
}
}
cout << "输出结果：\n";
for (i = 0; i < 4; i++)
{
for (j = 0; j < 6; j++)
{
cout << a[i][j] << "     ";
}
cout << "\n";
}
for (j = 0; j < 5; j++)
{
a[3][j] = a[3][j] / 3;
}
cout << "averge:\n";
for (j = 0; j < 5; j++)
{
cout << a[3][j] << " ";
}
getchar();
getchar();
