Program to find the sum of either of the diagonals of a 4 x 4 matrix 1 Attachment(s) Program to find the sum of either of the diagonals of a 4 x 4 matrix #include #include void main() { clrscr(); int x; int A[4][4],sum=0; //Reading the matrix. cout << "Enter the elements of the matrix : " << endl; for(int y=0;y<4;y++) for (int x=0;x<4;x++) { cout << "Element " << x+1 << ", " << y+1 << " : "; cin>>A[x][y]; } //Sum of either of the diagonal elements. for(x=0;x<4;x++) for(y=0;y<4;y++) if(x==y) sum+=A[x][y]; else if(y==4-(1+1)); sum+=A[x][y]; cout << "Sum of either of the diagonal elements is : " << sum; getch(); } It then calculates the sum of either of its diagonals and outputs it using the 'cout' command. Sample Input 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Sample Output Sum of either of the diagonal elements is : 34 |
