用代码块功能插入代码，请勿粘贴截图

我想要达到的结果

#include<stdio.h>
int main()
{ int n,m,i,j,k,t;
  while(scanf("%d",&n)!=EOF)
  { int a[n][n];
    for(i=0;i<n;i++)
     { for(j=0;j<n;j++)
        { scanf("%d",&a[i][j]);
         } 
     }
     for(t=0,i=0;i<n;i++)
      { for(j=0;j<n;j++)
        if(i==j) {
        }
        else { t=a[i][j];
               a[i][j]=a[j][i];
               a[j][i]=t;  
             }
        printf("%d ",a[i][j]);
        
      }
  }
    return 0;
}

供参考：

#include <stdio.h>
#define N 10
void InputMatrix(int* a, int Row, int Col)//输入矩阵元素
{
     int i,j;
     for (i = 0; i < Row; i++)
        for (j = 0; j < Col; j++)
            scanf("%d", a + i * Col + j);
}
void TransMatrix(int* a, int Row, int Col)//矩阵转置
{
    int i,j,tmp;
    for(i = 0; i < Row; i++){
        for(j = i; j < Col; j++){
            tmp = *(a + i * Col + j);
            *(a + i * Col + j) = *(a + j * Row + i);
            *(a + j * Row + i) = tmp;
        }
    }
}
void PrintMatrix(int* a, int Row, int Col)//输出矩阵
{
    int i, j;
    for (i = 0; i < Row; i++){
        for (j = 0; j < Col; j++)
        {
            printf(j==0? "%d":" %d", *(a + i * Col + j));
        }
        printf("\n");
    }
}
 
int main()
{
    int a[N][N] = { 0 }, n = 3;
    while (scanf("%d", &n) == 1){
          InputMatrix(a[0], n, n);
          TransMatrix(a[0], n, n);
          PrintMatrix(a[0], n, n);
    }
    return 0;
}
