Question

multiplication of two numbers using pointer with function in c language ?​

Answer 1

Answer:

#include <stdio.h>

#include <stdlib.h>

int multiplyNum(int , int);//function declaration or prototype

int main()

{

int num1,num2,product;//variable declaration

printf("Enter the two number ");

scanf("%d %d",&num1,&num2);//taking two number as input from user

product=multiplyNum(num1,num2);//calling the function

//The product value (returned by the function) is stored in product variable.

printf("The product of these numbers :%d",product);

//display the product value

getch();

return 0;

}

int multiplyNum(int a, int b)//defining function based in declaration

{

int result=a*b;//find product of two numbers

//and result stored in result variable

return result;//returning result

}

Answer 2

Answer:

Create two variables to store two numbers as input (num1 and num2) provided by the user. Create a variable to store the sum of these numbers: sum. Using scanf() function, store the second input value in num2.
