it works perfectly when i run it in vs code terminal thing but when i open the batch file it exits after entering the value of c
edit: the code i posted is only the start and the remaining code is 100% correct because i test it many times in terminal in vs code and it works

Answer 1

The file is correctly executed. When you open the batch file, the program reaches the end at the return 0 istruction (immediatly after you enter c). This operation is so fast that apparently is invisible, but the program is executed correctly. The reason why you can see it into the terminal, is because the terminal doesn't clear the prints.
