Write the c++ code that reads an integer from the user, and then computes that integer's absolute value.

Following are the program in C++

#include <iostream>// header file

using namespace std;

int main() // main function

{

   int num; // variable declarartion

   cout<<" Enter the number:";

   cin>>num; // user input

   num=abs(num); // finding the absolute

   cout<<num; // display number

   return 0;

}

Output:

Enter the number:-90

90

Explanation:

In this program we have declared a variable "num" of type int. After that we find the absolute value by using abs function and finally display the variable "num".
