How to add two numbers without using semicolon n c????
In this problem you are to write a program that will cut some number of prime numbers from the list of prime numbers between 1 and N.Your program will read in a number N; determine the list of prime numbers between 1 and N; and print the C*2 prime numbers from the center of the list if there are an even number of prime numbers or (C*2)-1 prime numbers from the center of the list if there are an odd number of prime numbers in the list.
