Program to Find the Transpose of a Matrix [C, C++, Python & Java]

Here, in this tutorial, we will write a program in C, C++, Python, and Java to transpose a matrix.

To write the program, you must know how to transpose a matrix, the for loop, and the programming language syntax.

Before we write the program, let us understand what is the transpose of a matrix.

What is the Transpose of a Matrix?

The transpose of a given matrix is obtained by interchanging its rows into columns and columns into rows.

For example: Consider a matrix A.

3       4       3
5       7       8
9       1       2

The transpose of the upper matrix would be:

3       5       9
4       7       1
3       8       2

C Program to Transpose a Matrix

#include<stdio.h>
int main()
{
    int arr[10][10],r,c, i, j;
    printf("Enter the number of rows: ");
    scanf("%d", &r);
    printf("Enter the number of Columns: ");
    scanf("%d", &c);
    printf("Enter the matrix element:\n");
    for(i=0;i<c;i++)
    {
        for(j=0; j<r; j++)
        {
            scanf("%d", &arr[i][j]);
        }
    }
    printf("The transpose of the matrix would be\n");
    for(i=0;i<c;i++)
    {
        for(j=0;j<r;j++)
        {
            printf("%d \t", arr[j][i]);
        }
        printf("\n");
    }
    return 0;
}

Output:

Enter the number of rows: 3
Enter the number of Columns: 3
Enter the matrix element:
3 4 3 5 7 8 9 1 2 
The transpose of the matrix would be
3       5       9 
4       7       1 
3       8       2 

C++ Program to Transpose a Matrix

#include<iostream>
using namespace std;
int main()
{
    int arr[10][10],r,c, i, j;
    cout<<"Enter the number of rows: ";
    cin>>r;
    cout<<"Enter the number of Columns: ";
    cin>>c;
    cout<<"Enter the matrix elements:\n";
    for(i=0;i<c;i++)
    {
        for(j=0; j<r; j++)
        {
            cin>>arr[i][j];
        }
    }
    cout<<"The transpose of the matrix would be\n";
    for(i=0;i<c;i++)
    {
        for(j=0;j<r;j++)
        {
            cout<<arr[j][i]<<" ";
        }
        cout<<endl;
    }
    return 0;
}

Output:

Enter the number of rows: 3
Enter the number of Columns: 3
Enter the matrix elements:
1 2 3 9 8 7 4 5 6
The transpose of the matrix would be
1 9 4 
2 8 5 
3 7 6 

Python Program to Transpose a Matrix

a=[]
arr =[]
r= int(input("Enter the number of rows: "))
c= int(input("Enter the number id Columns: "))
print("Enter the matrix elements")
for i in range(r):         
    a =[]
    for j in range(c):     
        a.append(int(input()))
    arr.append(a)
print("The transpose of the matrix would be")
for i in range(c):
    for j in range(r):
        print(arr[j][i],end=" ")
    print()

Output:

Enter the number of rows: 3
Enter the number id Columns: 3
Enter the matrix elements

12
23
12
34
45
65
47
23
877

The transpose of the matrix would be

12 34 47
23 45 23
12 65 877

Java Program to Transpose a Matrix

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        int arr[][] = new int[50][50];
        int r, c, i, j;
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter the number of rows: ");
        r = sc.nextInt();
        System.out.println("Enter the number of columns: ");
        c = sc.nextInt();
        System.out.println("Enter the matrix elements:\n");
        for (i = 0; i < r; i++) {
            for (j = 0; j < c; j++) {
                arr[i][j] = sc.nextInt();
            }
        }
        System.out.println("The transpose of the matrix is:\n");
        for (i = 0; i < c; i++) {
            for (j = 0; j < r; j++) {
                System.out.print(arr[j][i] + " ");
            }
            System.out.println();
        }
    }
}

Output:

Enter the number of rows: 
3
Enter the number of columns: 
3
Enter the matrix elements:

3 4 5 6 1 2 3 9 8
The transpose of the matrix is:

3 6 3 
4 1 9 
5 2 8 

Conclusion

We hope you have understood how to find the transpose of a matrix. We asked the user to enter the number of rows and columns of a matrix and its elements. We performed the transformation of the matrix generated by the user input.

Be extremely careful about for loops you use in the program. Otherwise, you may get an incorrect output. Understand the logic and implement it yourself.
