How to use Conditional Statements
Conditional statements are used to decide the flow of execution based on different conditions. If a condition is true, you can perform one action and if the condition is false, you can perform another action.

If statement If…Else statement If…Else If…Else statement
If statement
Syntax:
if (condition)
{
lines of code to be executed if condition is true

If…Else statement
Syntax:
if (condition)
{
lines of code to be executed if the condition is true
}
else
{
lines of code to be executed if the condition is false
}

If…Else If…Else statement
Syntax:
if (condition1)
{
lines of code to be executed if condition1 is true

else if(condition2)
{
lines of code to be executed if condition2 is true
}
