program to perform Scalar matrix multiplication

Write a C program to read elements in a matrix and perform scalar multiplication of matrix. C program for scalar multiplication of matrix. How to perform scalar matrix multiplication in C programming.
 
#include <stdio.h>

#define SIZE 3 // Maximum size of the array

int main()
{
    int A[SIZE][SIZE]; 
    int x, row, col;

    /* Input elements in matrix from user */
    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]);
        }
    }

    /* Input multiplier from user */
    printf("Enter any number to multiply with matrix A: ");
    scanf("%d", &x);

    /* Perform scalar multiplication of matrix */
    for(row=0; row<SIZE; row++)

C++ Language Find Largest of 2 Numbers - To find the largest number of the 2 numbers in C++, enter 2 numbers and checking which one is larger to "Display the Largest" on the output screen as shown here in the program

Partition of a Number in all Possible Ways - C++ Program to get all the unique partitions of an integer such that addition of a partition results an integer. An integer n, generate all "possible unique" ways to represent n as sum

Code Finds Maximum Between 2 Numbers - Finding maximum in general is comparison of two numbers. In C programming we compare two quantities using relational operator. Use either > or < operator to compare 2 numbers

Reads Strings from a File in Reverse Order - Program code to find out how many strings there are. Read string length. Check buffer is large enough and increase if necessary. Now get the position for the beginning of each...

Get Total Number of Notes in an Amount - C program to input amount from user & print minimum number of notes (Rs. 500, 100, 50, 20, 10, 5, 2, 1) required for the amount. Input amount from user. Store it in a variable 'amt'.

Program code to Reverse a Given Number - Take the Number which you have to Reverse as the input. Obtain its quotient & remainder. Multiply the separate variable with 10 & add the obtained remainder to it. Do step 2 again

Implement Slicker Algorithm that Avoids - Program to find the "Area of Ploygon" using "Slicker Algorithm". algorithm assumes the usual mathematical convention that positive y points upwards. Enter the number of points

Undirected Graph is Connected Using DFS - A "Recursive Function" to print 'DFS' starting from v. Returns reverse ('or transpose') of this graph. Add edge to connect v and w. Check if Graph is Connected and display 'The Graph is
