If-else Statement in C++

if-else statement
if statement is most commonly used with the following format:

1 2 3 4 5 6 7 8

if(expression) { statement 1 } else { statement 2 }

where else part is optional.

In this case, either of the two statements are executed depending upon the value of the expression. If the expression has a non-zero value (i.e., if the expression is true), then statement1 will be executed. Otherwise (i.e., if expression is false), statement2will be executed.

Example:
Given here is a program which reads a number and then prints whether the given number is even or odd.

Note: If we divide a number by 2 and if the remainder is 0 then the number is EVEN else the number is ODD

C++

1 2 3 4 5 6 7 8 9 10 11 12

#include<iostream.h> void main() { int n; cout << "Enter a number :"; cin >> n;   if(n%2 == 0) cout << "The number is EVEN"; else cout << "The number is ODD"; }
