Please write this program in C++ and explain it clearly! Thank you!

This project will familiarize the student with if, if -else, and while statements. Write a program that calculates the equivalent resistance of a network of series or parallel resistors. The program should prompt for the following input: parallel or series calculation? Loop for the number of elements (either enter the number of resistors, or terminate the value-entering loop with a sentinel value.. if you insist.) The value of each resistor After calculating the equivalent resistance, the program should output this value. Make use of one or more of the following control statements: 'if/else' statement 'while' loop Parallel: R_equivalent = 1/1/R_1 + 1/R_2 + ... + 1/R_N, and R_equivalent = R_1 + R_2 + .. + R_N, where N is the number of resisters
