CSE 1321L: Programming and Problem Solving I Lab

Lab 6

Loop Structures

Exercise #1: Design and implement a program (name it PrintSum) that prompts the user for an integer values between 1 and 100. The program then uses a while loop to determine and print out the sum of all values between 1 and the entered value. The program rejects invalid input values with proper message such "Invalid Input. Try again." Document your code and properly label the input prompt and the outputs as shown below.

Sample run 1:

You entered: 10
Sum of values: 55

Sample run 2:

You entered: 120
Invalid input. Try again.

Sample run 3:

You entered: 20
Sum of values: 210

Exercise #2: Design and implement a programming (name it EvenOdd) that uses a while loop to determine and print out all even numbers between 50 and 100 on a single line, separated by commas. Then another while loop in the same program to print out all odd numbers between 50 and 100 on a new line, separated by commas. Document your code and properly label the outputs as shown below.

Even numbers between 50 and 100: 50, 52, 54, 56, 58, 60, 62, 64, ...

Odd numbers between 50 and 100: 51, 53, 55, 57, 59, 61, 63, 65, ...

Exercise #3: (RandomNumbers) Write a for loop that will generate and display 10 random numbers from 1 to 50. Output all of the randomly generated numbers.

Instructions:

1. Programs must be working correctly.
2. Programs must be completed and checked before working the assignment.
3. Programs must be checked by the end of the designated lab session.
