Answer:
In C++:
#include <iostream>
using namespace std;
void function1(); void function2();
int main(){
function1(); function2();
return 0;}
void function1(){
cout<<"This is the first part of my program."<<endl<<"It was created with a function"<<endl;}
void function2(){
cout<<"This is the second part of my program."<<endl<<"It was created with a different function.";}
Explanation:
This defines the function prototypes
void function1(); void function2();
The main begins here
int main(){
This calls the two functions from main
function1(); function2();
return 0;}
This calls function1()
<em>void function1(){</em>
<em> cout<<"This is the first part of my program."<<endl<<"It was created with a function"<<endl;}</em>
This calls function2()
<em>void function2(){</em>
<em> cout<<"This is the second part of my program."<<endl<<"It was created with a different function.";}</em>
Answer:
The output will be as following:-
2
0
0
Explanation:
The function doSomething accepts the argument as reference.So whatever changes are made in the function to the argument the changes will be reflected onto the original arguments.
First the value of x is 2.Hence 2 is printed first.
Then function doSomething is called that changes the value of x from 2 to 0 and then prints it.Hence 0 is printed in the newline.
Then in the main function x is printed again the function changed it's value so 0 is printed.
