Transpose of matrix

Program:

#include<stdio.h>
int main()
{
int a[4][4],n,i,j;
printf("Enter value of n: ");    /*rows and cols*/
scanf("%d",&n);
printf("Enter matrix A row-wise: \n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
printf("a[%d][%d]=  ",i,j);
scanf("%d",&a[i][j]);
}
printf("\n");
}
printf("Matrix A : \n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
printf("%4d",a[i][j]);
}
printf("\n");
}

printf("Transpose of Matrix A: \n");
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
printf("%4d",a[j][i]);
}
printf("\n");
}

return 0;

}

Output:
