C program to find transpose of a matrix

Hello I want to discuss about the c program for transpose of the matrix.
Transpose matrix means interchange the rows with the columns and columns with the rows.

Program Code

#include < stdio.h >
#include < conio.h >
void main()
{
int arr[3][3],i,j;
clrscr();
printf("Enter elements for the array \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
scanf("%d",&arr[i][j]);
}
}
printf("Original array entered by the user is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
{
printf("%d ",arr[i][j]);
}
printf("\n");
}
printf("\n Transpose of the array is \n");
for(i=0;i < 3;i++)
{
for(j=0;j < 3;j++)
printf("%d ",arr[j][i]);
printf("\n");
}
getch();
}

Input:

Enter elements for the array
1
2
3
4
5
6
7
8
9

Output:

Original array entered by the user is
1 2 3
4 5 6
7 8 9

Transpose of the array is
1 4 7
2 5 8
3 6 9
