Conditional statements

CONDITIONAL STATEMENTS:
Conditional statements are used to make decisions based on a given condition. If the condition
evaluates to True, a set of statements is executed, otherwise another set of statements is executed.
And it is also known as decision statement.
There five types of conditional statements.
 if statement
 if else
 if else-if
 Switch statement
 Conditional operator

If statement:
If statement selects and executes the statement based on a given condition. If the condition evaluates
to True then a given set of statement is executed. However, if the condition evaluates to False, then
the given set of statement is skipped and the statement that are followed by if statement are executed.
For example:
x=6;
If(x>2)
{
cout<< x;
}
cout<< “x is an integer”;

If-else statement:
If-else statement comprises two parts, namely, if and else. If the condition is True, if part is executed.
However, if the condition is False, the else part is executed.
For example:
if(x>2)
{
cout<< “x is greater than 2”;
}
else
{
cout<< “x not greater than 2”;
}

IF ELSE-IF STATEMENT:
The if-else statement is used when we have two conditions. However, if we have more than two conditions or
choices, we used if else-if statement.
if (condition)
{
Statement(s);
}
else if (condition)
{
Statement(s);
}
else
{
Statement(s);
}

For example:
int x;
x=2;
if (x= = 0)
{
cout<< “it is equal to zero”;
}
else if (x>0)
{
cout<< “it is positive number”;
}
else
{
cout<< “it is negative number”;
}
