Assume that the discriminant (the portion of the formula inside the square root) is nonnegative. The program should also print a label showing all of the input data and the two solutions. Program Specifics: 1. Include a comment after each #include directive indicating what the header file is used for 2. Declare all variables after int main( ) . 3. Declare a string constant for your label border (the line of %’s). You may declare the constant before int main( ) . 4. Include a comment after each constant and variable declaration indicating what the constant or variable represents. 5. Make sure that you prompt the user for each individual piece of data that is entered. 6. Follow C++ conventions for naming constants, variables and functions. 7. Use at least two value-returning functions to do the calculations. 8. Use value-returning functions for all calculations. No calculation should appear inside the main function. 9. The values for x should be printed with one decimal point. 10. Include preconditions and postconditions for each function. Write the preconditions and postconditions between the function heading and the function body. 11. Put a comment indicating the declaration section, input section, processing section and output section of your program. Separate the sections with a blank line. 12. The output section of your program should use setw rather than using spaces inside quotation marks. 13. Use indentation so that the program is easy to read. COSC1415/1436 Program 2 Page 2 of 2 Output Include user prompts and user input. The output section of your program should produce output that looks very similar to the following: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Quadratic Formula a = 2 b = -4 c = -16 When adding the discriminant x = 4.0 When adding the discriminant x = 4....
