How can you use the do/while loop to cout all the prime numbers until 100 in c++?

#include <iostream> #include <cmath> using namespace std; bool isPrime(unsigned n) { for(unsigned i=2; i<=sqrt(n); i++) if(n%i==0) return 0; return 1; } int main() { unsigned x=2; do { if(isPrime(x)) cout<<x<<endl; x++; } while(x<100); return 0; }

Here is a Algorithm to print all prime numbers between 1 to N For every number i, between 2 to N/2(2<= i <= N/2) check whether i divides N completely(check If i is a factor of N). If none of the number between 2 to N/2 divides N completely then N is a prime number.
