computer science C++ questions

Given that two int variables, total and amount , have been declared, write a sequence of statements that:
initializes total to 0
reads three values into amount , one at a time.
After each value is read in to amount , it is added to the value in total (that is, total is incremented by the value in amount ).
Instructor's notes: If you use a loop, it must be a for loop.
And if you use a loop control variable for counting, you must declare it.
Given that two int variables, total and amount, have been declared, write a loop that reads integers into amount and adds all the non-negative values into total. The loop terminates when a value less than 0 is read into amount. Don't forget to initialize total to 0.
Instructor's notes: This problem requires either a while or a do-while loop.
Given an int variable n that has already been declared and initialized to a positive value, and another int variable j that has already been declared, use a do...while loop to print a single line consisting of n asterisks. Thus if n contains 5, five asterisks will be printed. Use no variables other than n and j .
Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a do...while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total . Thus if n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into total . Use no variables other than n , k , and total .
