4. Write C++ code to:
   • Create a function called “ReadFile” that:
     • Accepts a filename as input
     • Opens the file for reading
     • Reads an integer from the file and returns it.
   • Create a main function that
     • Asks the user to input a file
     • Passes that file to the “ReadFile” function

Answer 1

#include<iostream>
#include <fstream>
using namespace std;
int ReadFile(string name){
 fstream inputFile;
 int num;
  //opening the file
 inputFile.open(name);
 //reading num
 inputFile >> num;
 //returning num
 return num;
}
int main(){
        cout<<ReadFile("input.txt");
}
