Question

Please use C !!!

Write a C function matrixTranspose that takes a two-dimensional array as its input argument then transposes its elements and prints the results.

456 3 6 3 2

Develop the matrixTranspose method with two different methods:
1. Assume the matrix is a square matrix. This will make finding the transpose a simple swapping of the arrays’ elements and it can be done in place.
2. Generalize your function to work with any NxM matrix where N≠M. You will need to properly handle dynamic memory allocation for creating the transpose matrix inside the function.

Answer 1

Code:

#include<stdio.h>
void matrixTranspose(int *mat,int *trans,int r,int c){
   int i,j,k=0;
   for(i=0;i<r;i++){
       for(j=0;j<c;j++){
           trans[j*r+i]=mat[k++];                      //assigning main matrix values to transposed

                                                              //matrix with transposed   indexes.
       }
   }
}
int main(){
   int i,j,r,c;
   printf("matrix size: ");
   scanf("%d%d",&r,&c);                               //taking row and column size from user
   int mat[r][c],trans[c][r];                          //declaring matrix and transpose matrix with reverse dimensions
   printf("enter matrix:\n");
   for(i=0;i<r;i++){
       for(j=0;j<c;j++){
           scanf("%d",&mat[i][j]);                       //taking values for main matrix from user
       }
   }
   matrixTranspose(mat,trans,r,c);                       //passing addresses of main matrix and transpose matrix to matrixTranspose() function
   printf("Transpose matrix is:\n");
   for(i=0;i<c;i++){              
       for(j=0;j<r;j++){
           printf("%d ",trans[i][j]);                   //after completion of function calling main matrix transposed values strored in transpose matrix, printing those values.
       }
       printf("\n");
   }
}
