Example for ‘if’ statement:

# include <iostream.h>

void main ()

{

int a = 100;

int b = 200;

if (b > a)

{

cout <<"B is greater than A";

}

}

Result:

B is greater than A In the above example the condition in the if statement returns a true value and so the text “B is greater than A” is displayed. 

Example for ‘if else’ statement:

#include <iostream.h>

void main ()

{

int a = 10;

int b = 20;

if(a>b)

{

cout <<"A is greater than B";

}

else

{

cout <<"B is greater than A";

}

Result: B is greater than A. In the above example, the “if’ condition is false so the code in the “else” part is executed.
