Write a C++ program illustrating Swapping integer values by reference.

#include<iostream.h>
#include<conio.h>
void swap (int &a, int &b)
{
/* &a and &b are reference variables */
int temp;
temp=a;
a=b;
b=temp;
}
main()
{
clrscr();
int i=5,j=10;
cout<<"Before swapping I = "<<i<<" J = "<<j<<endl;
swap(i,j);
cout<<"After swapping I = "<<i<<" J = "<<j<<endl;
}

Write a C++ program illustrating Variable Scope

A scope is a region of the program and broadly speaking there are three places, where variables can be declared:

· Inside a function or a block which is called local variables,

· In the definition of function parameters which is called formal parameters.

· Outside of all functions which is called global variables.

Local Variables:

Variables that are declared inside a function or block are local variables. They can be used only by statements that are inside that function or block of code. Local variables are not known to functions outside their own. Following is the example using local variables:

#include <iostream>

int main ()

{

// Local variable declaration:

int a, b;

int c;

// actual initialization

a = 10;

b = 20;

c = a + b;

cout << c;

return 0;

}

Global Variables:

Global variables are defined outside of all the functions, usually on top of the program. The global variables will hold their value throughout the life-time of your program.

A global variable can be accessed by any function. That is, a global variable is available for use throughout your entire program after its declaration. Following is the example using global and local variables:

#include <iostream>

// Global variable declaration:

int g;

 int main ()

  // Local variable declaration:

  int a, b;

  // actual initialization

  a = 10;

  b = 20;

  g = a + b;

  cout << g;

  return 0;

A program can have same name for local and global variables but value of local variable inside a function will take preference. For example:

#include <iostream>

// Global variable declaration:

int g = 20;

int main ()

{

// Local variable declaration:

int g = 10;

cout << g;

return 0;

}
