Write a C program to accept a matrix of size m x n and display transpose of a given matrix.

 #include <stdio.h>
int main() 
{
  int a[10][10], transpose[10][10], r, c,i,j;
  printf("Enter rows and columns: ");
  scanf("%d %d", &r, &c);
  // asssigning elements to the matrix
  printf("\nEnter matrix elements:\n");
  for (i = 0; i < r; ++i)
  for (j = 0; j < c; ++j) 
  {
    printf("Enter element a[%d][%d]\t", i + 1, j + 1);
    scanf("%d", &a[i][j]);
  }
  // printing the matrix a[][]
  printf("\nEntered 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");
  }
  // computing the transpose
  for (i = 0; i < r; ++i)
  for (j = 0; j < c; ++j) 
  {
    transpose[j][i] = a[i][j];
  }
  // printing the transpose
  printf("\nTranspose of the matrix:\n");
  for (i = 0; i < c; ++i)
  for (j = 0; j < r; ++j) 
  {
    printf("%d  ", transpose[i][j]);
    if (j == r - 1)
    printf("\n");
  }
  return 0;
}

OUTPUT:

Enter rows and columns: 3

2

Enter matrix elements:

Enter element a[1][1]   5

Enter element a[1][2]   2

Enter element a[2][1]   3

Enter element a[2][2]   4

Enter element a[3][1]   5

Enter element a[3][2]   9

Entered matrix:

5  2

3  4

5  9

Transpose of the matrix:

5  3  5

2  4  9
