# A10.m - Finding first N primes (using a while loop with an if statement)

% get info from user N = input('How many prime numbers do you want to find? '); n = 1; % n will step through every integer until N primes are found nPrimes = 0; % nPrimes will count the number of prime numbers found while nPrimes < N % while loop goes until nPrimes = N, then it stops if isprime(n) fprintf('%i\n',n) % display prime numbers to command % window as they are found nPrimes = nPrimes + 1; % increment the number of primes found end n = n + 1; % increment the number counter end

A simple example of using a while loop combined with an if statement.
