My code in c is giving wrong output -


i wrote code in c, find largest prime factor of number i, , gives j=5102831, prime not factor of i.

the code seems write me, feels there wrong compiler.

so, please copy code , check output it's giving.

#include <stdio.h>  int prime (int);  int main() {     int i=600851475143,j;      j=i-1;    ( ; ; j--)         {             if ((i%j) ==0)                 if(prime(j))                     return (j);             if (j==2)                 break;         }     return 0; }  int prime (int j) {     int k;     for(k=2; k<=j-1; k++)         if((j%k)==0)             return 0;     return 1; }

i think mean

        if ((i%j) !=0)                   ^^^             if(prime(j))                 return (j);

also take account 2 prime number.
