Use a while loop to convert time in minutes to time in hours and minutes. Use #define or const to create a symbolic constant for 60, and provide a sensible method of ending the loop.
Write a program that asks for an integer and then prints all the integers from (and including) that value up to (and including) a value larger by 10. (That is, if the input is 5, the output runs from 5 to 15.)
Write a program that asks you to enter the number of days and then converts that value to weeks and days. For example, it would convert 18 days to 2 weeks, 4 days.
Change the program addemup.c (refer to Listing 5.13) that found the sum of the first 20 integers. (If you prefer, you can think of addemup.c as a program that calculates how much money you get in 20 days if you receive $1 the first day, $2 the second day, $3 the third day, and so on.) Modify the program so that you can tell it interactively how far the calculation should proceed. That is, replace the 20 with a variable that is read in.
Now modify the program so that it computes the sum of the squares of the integers. (If you prefer, how much money you receive if you get $1 the first day, $4 the second day, $9 the third day, and so on. This looks like a much better deal!) C doesn't have a squaring function, but you can use the fact that the square of n is n * n .
Write a program that requests a floating-point number and prints the value of the number cubed. Use a function of your own design to cube the value and print it. The main() program should pass the entered value to this function.
