To transpose a 2D array

#include<stdio.h>
#include<conio.h>
int main()
{
    int a[10][10], trans[10][10],r,c,i,j;
    printf("Enter the row and column of matrix :\n");
    scanf("%d%d",&r,&c);
    printf("\nEnter the element of 1st matrix : \n");
    for(i=0;i<r;i++)
        {
            for(j=0;j<c;j++)
            {
                printf("Enter element of 1st matrix %d%d: ",i,j);
                scanf("%d",&a[i][j]);
            }
        }
    printf("\nEnter matrix : \n");
    for(i=0;i<r;i++)
        {
            for(j=0;j<c;j++)
            {
                printf("%d",a[i][j]);
                if(j==c-1)
                {
                    printf("\n\n");
                }
            }
        }
   for(i=0;i<r;i++)
        {
            for(j=0;j<c;j++)
            {
              trans[j][i]=a[i][j];
            }
        }
    printf("\n Transpose of matrix : \n");
     for(i=0;i<r;i++)
        {
