#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
  string line;
  string s="Hello";
  ifstream myfile ("example.txt");
  if (myfile.is_open())
  {
    while ( myfile.good() )
    {
      getline (myfile,line);
      cout << line << endl;
      strcmp(s,line);   // Error line
    }
    myfile.close();
  }

  else cout << "Unable to open file"; 

  return 0;
}


I know strcmp is not there in std:: lib . But i want to compare these two string how i can compare them??
Hi Kalki , convert string to char array ( but char array is const char * so convert const char * to char *)

// Example program
#include <iostream>
#include <string>
#include <stdio.h>
#include <string.h>
using namespace std;
int main()
{
  string s = "test";
  char *c = "test";
  char *ch = (char*)s.c_str();
  cout << strcmp(c,ch) << endl;
  return 0;
}
Hi, use the == operator

Don't go backwards by casting to char *
