The Program in C++ Program to Create n x n matrix by taking an integer(n) is given below:
#include <iostream>
using namespace std;
int main() {
int n;
cout << "Hello Codeuari Family, Enter the size of the matrix (n x n) here to represent into matrix form: ";
cin >> n;
int matrix[n][n];
cout << "Well, enter the elements of the matrix here: " << endl;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
cin >> matrix[i][j];
}
}
cout << "Okay, the matrix is: " << endl;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
cout << matrix[i][j] << " ";
}
cout << endl;
}
return 0;
}
Output:
Hello Codeuari Family, Enter the size of the matrix (n x n) here to represent into matrix form: 3
Well, enter the elements of the matrix here:
1
9
6
7
8
4
5
6
7
7
2
Okay, the matrix is:
1 9 6
7 4 5
6 7 2
Pro-Tips💡
This program prompts the user to enter the size of the matrix and then the elements of the matrix.
The matrix is stored in a two-dimensional array named matrix.
Finally, the matrix is displayed by printing the elements of the array.
