I keep getting the expected expression error. How do I fix it?

making a program to find all the prime numbers up to a certain number.

I've tried changing the for loops and the if statement.

#include <iostream>

using namespace std;

int main(){
double x;
double y = 0;
cout << "Enter an input range: ";
cin >> x;
for (int i;i<=x;){
    for(int p;p<=i-1;i++){
        if(i%p==0;){
            break;
        }   else{
            y+=1;
            cout << i << " #" << y << endl;

        }
    }

}
return 0;

}
