You are given an integer N. You need to print the series of all prime numbers till N.
I want to know whats wrong with my code and suggestions will also be of great help.
#include<iostream>
using namespace std;
int main()
{
int N;
cin>>N;
int u;
for(int i=N;i>0;i--)
{
u=0;
for(int j=2;j<N-1;j++)
{
if(i%j==0)
{
u=1;
}
}
if(u==0)
{
cout<<i<<" ";
}
}
return 0;
}
Thanks for helping out. :)
