Create a c++ program to create a cvs file (graderepost. csv) with this structure: name, mat, phy, bio, chem. the program must show a menu of options like this: menu of options enter student name and grades print grade report exit when the user press 1, the program must allow them to enter the data of 1 student with 4 grades. after, the data entry is done. the program must go to the menu of options again. when the user enter 2, the program must print the grade report. the option 3 is to exit.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
