1. Write a program that contains and utilizes a function called haltNum(int&).
This function utilizes a call by reference. The function get an argument n and divides it by 2.
The program ask for a number, saved as entry , pass it on as an argument for halfNum(), then
print the result of halfNum(int & entry) on entry.
Solution
----Program Written in C++ Language
#include<iostream.h>
#include<conio.h>
int halfNum(int& n)
{
return(n/2);
}
void main()
{
clrscr();
int entry,result;
cout<<"enter value for entry ";
cin>>entry;
result=halfNum(& entry);
cout<<"Result= "<<result;
getch();
}
