please answer in a .c program using C++ language

only use and or and also CRT_SECURE_NO_WARNINGS

Once the moment of inertia has been determined, calculate the deflection from the formula: deflection = (PL)/(3EI). Print the deflection at the end of the beam in inches, in exponential notation, with 4 digits after the decimal point. When the program is working, modify it using a while or do...while loop so that the program will continue prompting the user to see if the program is to be run again for a different cross section and/or cross sectional dimensions. After the deflection is printed the user will be asked if he/she wants to do another deflection calculation. He/she might enter Y (or 1) to continue or N (or 2) to quit. 1. A cantilever beam (fixed at the left ead and free at the other) of length L is pictured below. It is subjected to load P = 200 lb at the end. Such loading results in deflection of the beam downward and a resulting curvature of the beam.

Write a program to calculate the deflection at the end of the beam (b) for a given cross section of the beam. Define E and PI as constants. Prompt the user to input a value for the length of the beam L. Restrict the length L of the beam to a value between 16 and 24 inches by using a while data validation loop. Print a menu for the user to select the type of cross section of the beam. The user should enter a letter corresponding to one of the following options: R===> rectangular cross section T ===> triangular cross section C===> circular cross section Use a switch statement to calculate the moment of inertial for the different cases according to the formulas shown below. Within each case, the user should be prompted to enter base, height, and/or radius as appropriate. IV DO Include a default for an improper choice. Also make sure your switch statement can accommodate both upper and lower case letters
