When are there circumstances in which it makes sense to employ union compatibility between two select statements that are made from the same table?

Design and implement a program in C++ that informs the user of the acceptance status of each candidate applying based on the qualifications stated above. The user will input a group of candidates at a time. For each candidate, they will provide sex, height & weight (The sex should be read into a single character variable). Each of the input values should be error-checked. (See below for the minimum and maximum constraints). For each candidate, the program will output whether each candidate was accepted, or rejected based on height, weight, or height & weight. The user will input ‘X’ or ‘x’ for the sex when they are finished entering in all the applicants. The program will output the number of candidates accepted and the percentage of candidates accepted. Run the code 3 times to test it (do not use a for loop for this).  • You must first write out a design for the code. It does not need to be created with a tool, but it    needs to be readable. You can use pseudocode or a…
