And in the comparison, we know that there are three conditions i.e. first value is greater than the second value, first value is less than the second value and first value is equal to the second value. Here in the above program construct the else part competes the greater than conditions and covers both less than and equal to conditions. Thus in the above program construct, the message "Amer is younger than Amara" is displayed even if Amer’s age is the same as Amara’s age. This is logically incorrect and so to make this correct, we should display the message "Amer is younger than or is of the same age as Amara". Now this statement describes both the cases other than the one ‘Amer is greater than Amara'. The use of else saves us from writing different if statements to compare different conditions, in this way it cover the range of checks to complete the comparison. If we want to state the condition "Amer is greater than or is of the same age as Amara’s" then we use the greater than or equal to operator (i.e. >=) in the if statement and less than operator ( < ) in the else statement to complete the comparison. It is very important to check all the conditions while making decisions for good, complete and logical results. Make sure that all cases are covered and there is no such case in which the program does not respond. The flow chart of our program with if/else structure will be as follow.
