can i get this answered please

LAB 5.3 LAB 5.3 Working with the Working with the for Loop Copy and paste the following program into Visual Studio IDE. // This program has the user input a number n and then finds the // mean of the first n positive integers #include using namespace std; int main() { int value; // value is some positive number n int total = 0; // total holds the sum of the first n positive numbers int number; // the amount of numbers float mean; // the average of the first n positive numbers do { cout << "Please enter a positive integer" << endl; cin >> value; } while (value <= 0); // First find the running total from 1 to value. for (number = 1; number <= value; number++) { total += number; } // curly braces are optional since there is only one statement // Then find the mean. Note the use of the typecast operator here. mean = static_cast(total) / value; cout << "The mean average of the first " << value << " positive integers is " << mean << endl; return 0; } Exercise 1: Why is the typecast operator needed to compute the mean in the statement mean=static_cast(float)(total)/value;? What do you think will happen if it is removed? Modify the code and try it. Record what happens. Make sure that you try both even and odd cases. Now put static_cast total back in the program. Exercise 2: Modify the code so that it computes the mean of the consecutive positive integers n, n+1, n+2, ..., m, where the user chooses n and m. For example, if the user enters 3 and 9, then the program should find the mean of 3, 4, 5, 6, 7, 8, and 9, which is 6. Print out the program and the running result for Exercise 2, and hand them in with the rest of the lab. Note: Print out two copies of running result, one for valid inputs and one for invalid inputs.
