Write your question here.
I want it to print the number i input however it only let me input number but it doesn't print out the result

#include <iostream>
using namespace std;
int myabs(int val);
int main()
{
int val;
cout << "Input a number ";
cin >> val;
int myabs(val);
}

may I ask, where you print the number out? Because you use cout to print things out, and I dont see a cout after you have taken the input.

int myabs(val); This doesnt do anything.

Doesnt look like you know how functions work. Watch video 9-11.

You need to define

int myabs (int val);

after main. Right now you have declared it but it has no definition and thus does nothing when called.

int myabs()
{
      // Put some code here
}
