in c++

1. Write a complete program (using only while loops) that prints the integers from I to 100 to the monitor, with 10 integers being printed on each line, similar to the following: (Values must be lined up by last digit) 3.10 20 11 12 13 91 92 93100 2. Write a void function that receives two integer parameters, the total amount of money from a customer, and the item's price. The function will print the change to be given back to the customer in 10s, 5s and single dollar bills. (You must always retun the most number of 10's possible) 3. Write a value-retuming funsction that computes the volume of a right square pyramid given the side of its function that computes the volume of a right square pyramid given the side of base and its height (formula is , and write a sompletc program that includes a function, and prints the volume, in a while or do-while loop that is executed as long as the user types in y or Y' asa response to a question printed to the screen. Write a program You can only use" or "in a cout statement. Assume the number of rows is at least 3,. 4. that produces this diagram for a user-specified number of rows (The number of columns is fixed) 5. Write a function whose arguments are an array and an integer representing the size of the array. The function will load the array with random values from 4 to 59, inclusive. (Meaning, the minimum number can be 4 and the maximum can be 59) Write a block of code that will keep on asking the user to "Enter a positive integer" as long as the user does not enter one. 6
