行列互换，也就是将
a[i][j]的数据 放到b[j][i]上。
对于初学者，用第二个矩阵最简单了。
于是
int main()
{
int a[4][4],b[4][4];
int i,j;
for(i = 0; i < 4; i ++)
for(j = 0; j < 4; j ++)
scanf("%d",&a[i][j]);
for(i = 0; i < 4; i ++)
for(j = 0; j < 4; j ++)
b[i][j] = a[j][i];
for(i = 0; i < 4; i ++)
{
for(j = 0; j < 4; j ++)
printf("%d,",b[i][j]);
printf("
");
}
return 0;
}
这样就可以了。
