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
