c++ programing if else condition,

 

If/else Structure

We have seen that the if structure executes its block of statement(s) only when the condition is true, otherwise the statements are skipped. The if/else structure allows the programmer to specify that a different block of statement(s) is to be executed when the condition is false. The structure of if/else selection is as follows.

/* This program checks the age of Amer and Amara’s and

displays the appropriate the message. The program is using

two if statements.*/

# include <iostream.h>

main ( )

{

 int AmerAge, AmaraAge;

 //prompt the user to enter Amer’s age

cout << “Please enter Amer’s age “ ;

 cin >> AmerAge;

 //prompt the user to enter Amara’s age

 cout << “Please enter Amara’s age “ ;

 cin >> AmaraAge;

 //perform the test

 if (AmerAge > AmaraAge )

 {

 cout << “ Amer is older than Amara”;

 }

 if (AmerAge < AmaraAge )

 {

cout << “ Amer is younger than Amara”;

 }

}

Else

#include<iostream>

using namespace std;

main()

if (AmerAge > AmaraAge )

{

cout << " Amer is older than Amara";

}

else

{

cout << " Amer is younger than Amara";

}
