4. What is a driver program? 43. Consider the following function and code segment. void Onet int first, int& second first 17 secondfirst 1 int main) // other code int j4; int k3; One(j, k) // other code .. After the call to OneGi, k); what are the values ofj and k?

Answer 1

Driver program:

Driver program is just a program that uses the class or algorithm that you're developing. It's primarily used for testing your code while you develop it.

Stub program:

A stub is a controllable replacement for an Existing Dependency in the system. By using a stub, you can test your code without dealing with the dependency directly.

code

====================================

#include <iostream>

using namespace std;
void One(int first ,int & second)
{
first = 17;
second = first + 1; //here k is added with 17 -->17+1=18.
}
int main()
{
int j = 4;
int k = 3;
One(j,k);
//Here j is passed by value and k is passed by reference
//So the value of j remains same even after the function calling and value of k changes
cout<<"j value: "<<j<<"\nK value:"<<k;
}
