please help

Question

I have this problem as homework and I don't know what is my mistake
A natural number n is read from the keyboard. Make the program that determines the sum of the elements less than or equal to n that are primes and palindromes.
#include <iostream>
using namespace std;

int main()
{
int n,ok,d,s,ogl,i,i1;
cin>>n;
for(i=1;i<=n;i++)
ok=1;
if(i==0 || i==1)
ok=0;
else
for(d=2;d<=i/2;d++)
if(i%d==0)
ok=0;
if(ok==1)
ogl=0;
i1=i;
while(i1!=0)
{ogl=ogl*10+i1%10;
i1=i1/10;
}
if(ogl==i)
s=s+i;
cout << s;
}

Answer 1

Either the code is badly indented or you are missing a lot of braces {} in your code.

Also I can see you have not initilised variable "s" so it will add up so some heavenly👼 value during execution.

Answer 2

I saw my mistakes now...
