Q1) How to use C code to write a C program segment to prompt a user for entering an integer and save it into an “option” variable. In your program, you have to make sure the value (option) entered by the user is either 1, 2 or 3 only. Otherwise, display a message asking the user to re-enter the “option” value. [Note: Assume that all the necessary variables have been declared]

Q1a) Instructions Consider the following program segment: //include statement(s)//using namespace statement int main(){//variable declaration //executable statements //return statement} Write a C++ statement that includes the header file iostream. Proceed through all the steps in this activity by clicking the navigation arrows at the bottom of this pane after completing each step. Write a C++ statement that allows you to use cin, cout, and endl without the prefix std::. Write C++ statement(s) that declare the following variables: num1, num2,num3, and average of type int. Write C++ statements that store 125 into num1, 28 into num2, and –25 into num3. Write a C++ statement that stores the average of num1, num2, and num3 into average. Final Step: Write C++ statement(s) that output the values of num1, num2, num3, and average. Then compile and run your program by clicking the blue run button on the right side of the screen.   Q1b) Write a program to implement and test the algorithm that you…
