Nested function classwork 2 Write 'taxIncome', a user-defined function that calculates income tax. y = taxincome (income) defines the principal function. The main function calculates adjusted income as income - 6000. Then y = compute Tax is called. For y = 0.28*Adjusted Income, this function uses 'Adjusted Income'. 'Adjusted Income' was defined in the main function. Use $80,000 income.
Write a program that prompts the user to enter two positive integers. Implement a function to validate the user input. The program will use a loop to re-prompt a user for an input until a user inserts a valid input. Implement a summation function.The program will sum those two integers and show a result on a terminal screen. The program must have a lease two functions. #1 Examples output: input1 - 7 input2 = 6 7+6 - 13 # 2 Examples output: input1 = 0 try again = -5 try again = 10 input2 - 6 10 + 6 - 16 Please fill in the source code below: #include using namespace std; int input); (int a, int b); int int input1= 0; int input2 = 0; cout<<"Input1 = "; input1 = (input1); cout<<"Input2 = "; input2 = getPositivelnput( átv S MacBook Air DII DD 80 888 F7 F8 F9 F4 F5 F6 F3 * & #3 2$ 7 CO
