C++ If Else Statement

In the if-else statement of C++ language, the condition in the parenthesis of if is evaluated for a boolean value - true or false.

If this condition is true then the statement or a block of statements connected to the if statement is executed.

If this condition is false then the statement or a block of statements connected to the else is executed.

if else example

 /* C++ if else example */

#include<iostream>

using namespace std;
int main()
{
if(10<50)
	cout<<"10 is less than 50";
else
	cout<<"10 is greater than 50";

return 0;
}

Output -

10 is less than 50

int

if-else

Another if else example

/* C++ if else example */

#include<iostream>

using namespace std;
int main()
{
//Declaring multiple char variables.
char a = 'a', b = 'b';

//An if-else statement comparing values in char variables
if(a<b)
	cout<<"a is less than b";
else
	cout<<"b is greater than a";

return 0;
}

Output -

a is less than b

In the latter program, we have compared values in char variables using an if-else statement, internally their ASCII values have been compared to find out which character has a greater ASCII value.
