C Program to Perform Scalar Matrix Multiplication

C Program to Perform Scalar Matrix Multiplication: This program allows the user to enter the number of rows and columns of a Matrix. Next, this C program to perform Scalar Multiplication on this matrix using For Loop.

C Program to Perform Scalar Matrix Multiplication

#include <stdio.h>
#define SIZE 3 
int main()
{
    int A[SIZE][SIZE]; 
    int num, row, col;
    printf("Enter elements in matrix of size %dx%d: \n", SIZE, SIZE);
    for(row=0; row<SIZE; row++)
    {
        for(col=0; col<SIZE; col++)
        {
            scanf("%d", &A[row][col]);
        }
    }
    printf("Enter any number to multiply with matrix A: ");
    scanf("%d", &num);
    for(row=0; row<SIZE; row++)
    {
        for(col=0; col<SIZE; col++)
        {
            A[row][col] = num * A[row][col];
        }
    }
    printf("\nResultant matrix c.A = \n");
    for(row=0; row<SIZE; row++)
    {
        for(col=0; col<SIZE; col++)
        {
            printf("%d ", A[row][col]);
        }
        printf("\n");
    }
    return 0;
}

Output Of Program

Enter elements in matrix of size 3×3:
5*5
Enter any number to multiply with matrix A:
Resultant matrix c.A =
0 0 0
0 0 0
0 0 0
