C++ Program to Multiply Two Matrix
Write C++ Program to Multiply Two Matrix
// CPP Program to Multiply Two Matrix #include <iostream> using namespace std; int main() { int A[3][3]={{1, 1, 1}, {2, 2, 2}, {3, 3, 3}}; int B[3][3]={{1, 1, 1}, {2, 2, 2}, {3, 3, 3}}; int i, j, k, C[3][3]; cout << "Matrix A :--> \n"; for(i = 0;i < 3; i++) { for( j = 0; j < 3; j++) { cout << A[i][j] << " "; } cout << endl; } cout << "\n\nMatrix B :--> \n"; for(i = 0;i < 3; i++) { for( j = 0; j < 3; j++) { cout << B[i][j] << " "; } cout << endl; } // Multiplying Matrix for(i =0 ;i < 3; i++) { for(j = 0;j < 3; j++) { C[i][j]=0; for(k = 0; k < 3; k++) { C[i][j] = C[i][j] + (A[i][k] * B[k][j]); } } } cout << "\n\nResultant Matrix :--> \n"; for(i = 0; i < 3; i++) { for(j = 0; j < 3; j++) { cout << C[i][j] << " "; } cout << endl; } return 0; }
Output:
Matrix A :-->
1 1 1
2 2 2
3 3 3
Matrix B :-->
1 1 1
2 2 2
3 3 3
Resultant Matrix :-->
6 6 6
12 12 12
