• kinds of loops - Examples
• counting loops
• Example: write a function that sums ten ints
• sentinel-controlled loops
• Example: write a function that averages ints until the user enters 0
• end-of-file-controlled loops
• Example: write a function that averages all the ints in a file
• input validation loops
• Example: write a function that keeps asking for a valid letter grade (A,B,C,D,F) until it receives one
• general conditional loops
• Example: write a function that sums ints as long as the sum is below 100
• for loops
• Example: re-write the first two examples above
• do-while loops
• Example: Write a function that repeatedly prompts the user and reads positive numbers until they enter a negative number. Return the sum of the positive numbers entered.
