            conditanals and conditional statments

            it allowes code to make decistions

            the statment that we will be useing the most is the if() else if() else

            these statments will be using the conditional operators

            <,>,<-,>-,-- (equal to),!-(not equal to)

            if() --> use if to spesify a block of code to be exacuted, if a spesified condition is true (if the expression in the () evaluates tp true, then excute the code in the ()

            else --> use the else to specify a block of code to be exacuted , if the same condition in the if is false(if the epression, if the same condiotion in the if is false (if the ecpressiom in the () evaluates to false, then excute the code in the ()

            else if() - use the else if() in a situation where you need to check for more than one condition after the first if() is false

            syntax

            if condiotion

            {

            code to excute if the condition is true

            }

            else if (second condition to evaluate if origanal condition is false)

            {

            code to excute if the 2nd condition is true

            you may havee as many else ifs()s as you need

            }

            else

            code to exacute if all other conditions are false
