Write a C program to transpose a m x n matrix

5.B) Write a C program to transpose a m x n matrix.

Answer:

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