Objective Question on C

The if-else Statement

if expression evaluates to true (anything other than 0), the statement or block that forms the target of if is executed; otherwise, the statement or block that is the target of else will be executed, if it exists. Remember, only the code associated with if or the code associated with else executes, never both.

The general form of if-else statement is :

if ( condition / expression )
{
Statements to be executed ;
.
.
}
else
{
Statements to be executed ;
.
.
}

printf("\n Entered number is greater than or equal to 10. ") ;

}
