Problems integrating while()loop into the if/else statement.

[jackbruns28]

Hey guys. Having trouble with some concepts. I think I've mostly got the while()loop concept figured out. But have a question. If I integrate the if/else statement into the loop, does it still terminate when the loop shuts off when hitting that sign? For example, if while(name!<90), then if I enter 90 the loop shuts off right? And if so, do the if/else statements shut off as well? Thank you. Here is a copy of what I am refering to.

Description

Write a program that computes the letter grades for the students in a class given their test scores. A student test score varies from 0 to 100. For each student, the program first asks the student’s name and then the student’s test score. It then displays the student name, test score and the letter grade. It repeats this process for each student.

The program calculates the letter grade from the test score as below:

A is 90 to 100 points

B is 80 to 89 points

C is 70 to 79 points

D is 60 to 69 points

F is 0 to 59 points.



/*

Java

*/

The user indicates the end of data by pressing the cancel button in the input dialog box when asked for a student name.



/*

C++

*/

The user indicates the end of data by entering two consecutive forward slashes ( // ) when asked for the name.





At the end, the program displays a summary report including the following:



· The total number of students.

· The total number of students receiving grade “A”.

· The total number of students receiving grade “B”.

· The total number of students receiving grade “C”.

· The total number of students receiving grade “D”.

· The total number of students receiving grade “F”.

For example, if while(name!<90), then if I enter 90 the loop shuts off right?

I think you meant (name<90). But anyway, the loop ends when the while condition is actually tested and found to be false. If there is a lot of code within the loop, all that code will continue to be executed until the closing brace } is encountered, then the condition is checked, and if it is false the loop will terminate.
