Multiplication of two number by using C Programs

Multiplication of two number by using C Programs

 Let's Understand Step by Step:

Algorithm:

1. Start: Take two numbers, $a$ and $b$.

2. Initialize: Set a result variable, $result$, to 0.

3. Loop: Iterate until one of the numbers (say $b$) is 0.

   • If $b$ is odd, add $a$ to $result$.

   • Double $a$ (i.e., $a=a\times 2$).

   • Halve $b$ (i.e., $b=b\mathrm{/}2$).

4. End: The $result$ now contains the product of $a$ and $b$.

 

Flow chart:

             

Program for multiplication:

  

#include<stdio.h>

int main()

{

    int a,b,c;

   

printf("enter two number:");

   

scanf("%d %d", &a,&b);

   

c = a * b;

   

printf("multiplication of %d * %d is %d", a,b,c);

return 0;

}

Output:

enter two number:12

12

multiplication of 12 * 12 is 144
