C++ Program to perform Matrix Transpose
You are Here:
Perform Matrix Transpose
In the following example, we will transpose the given matrix (two-dimensional array).
Example
C++ Compiler
#include <iostream>
using namespace std;
int main()
{
int i, j, n;
int arr[3][3] = {
{1, 1, 1},
{2, 2, 2},
{3, 3, 3}
};
cout << "Matrix (3 x 3):\n";
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
cout << arr[i][j] << " ";
cout <<"\n";
}
for(i=0; i<3; i++)
{
for(j=i+1; j<3; j++)
{
n = arr[i][j];
arr[i][j] = arr[j][i];
arr[j][i] = n;
}
}
cout << "\nMatrix Transpose: \n";
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
cout << arr[i][j] << " ";
cout <<"\n";
}
return 0;
}
Output
Matrix (3 x 3):
1 1 1
2 2 2
3 3 3
Matrix Transpose:
1 2 3
1 2 3
1 2 3
In the following example, we will get the values for (3 x 3) Matrix from the user and display the transpose matrix.
Example
C++ Compiler
#include <iostream>
using namespace std;
int main()
{
int i, j, n, arr[3][3];
cout << "Enter Matrix (3 x 3):\n";
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
cin >> arr[i][j];
}
for(i=0; i<3; i++)
{
for(j=i+1; j<3; j++)
{
n = arr[i][j];
arr[i][j] = arr[j][i];
arr[j][i] = n;
}
}
cout << "\nMatrix Transpose: \n";
for(i=0; i<3; i++)
{
for(j=0; j<3; j++)
cout << arr[i][j] << " ";
cout <<"\n";
}
return 0;
}
Output
Enter Matrix (3 x 3):
1 2 3
6 7 9
4 5 7
Matrix Transpose:
1 6 4
2 7 5
3 9 7
