Chapter 5, Problem 36E

To determine

• The type of loop applied to sum the integers $1$ through $50$.

• The type of loop applied to add $3$ to all the numbers in a vector.

• The type of loop applied that prompts the user for a string and keep doing this until the string that the user enters is a keyword in MATLAB.

• The type of loop applied to find the minimum in every column of a matrix.

• The type of loop applied that prompts the user for $5$ numbers and find their sum.

• The type of loop applied that prompts the user for $10$ numbers, find the average, and also how many of the numbers were greater than the average.

• The type of loop applied that generates a random integer $n$ in the range from $10$ to $20$. Prompt the user for $n$ positive numbers, error-checking to make sure you get $n$ positive numbers (and one echo print each one).

• The type of loop applied that prompts the user for positive numbers until the user enters a negative number. Calculate and print the average of the positive numbers, or an error message if none are entered.
