Write a C program to perform the following tasks: In main: Input an integer and call a function to double it using call- by-value in function: Calculate and return double of integer argument

Solution

#include<stdio.h>

int doublenum(int x)// function that doubles the value of x

{

return 2*x;

}

void main()

{

int number,result;

printf(\"enter any integer\");//prompt to read a number

scanf(\"%d\",&number);// the input read through keyboard is stored at address of number
result=doublenum(number);//function call

printf(\"the number after doubling:%d\ \",result);

}

output:
