#include <stdio.h>
#include <string.h>

int search(char *q[], char *ne);

char *ne[] = {"Jon","J","Jae","games",NULL};

int main(void)
{
  if(search(names, "James") != -1)
    printf("in list.\n");

  if(search(names, "Bill") == -1)
    printf("not found.\n");

  return 0;
}

int search(char *q[], char *name)
{
  int t;

  for(t=0; p[t]; ++t){
    if(!strcmp(q[t], name)) {
       return t;
    }
  }
    return -1; /* not found */
}

#include <string.h>
main()
{
FILE *file;

        file = fopen("/home/jim/filename","f");
        if(file==NULL)
        {
        printf("error");
        }

}

Try this ;

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main () {

char* search = "b"; 
int offset; 
string line;
ifstream file;
Myfile.open ("file1.txt");

if(file.is_open())
{
while(file.eof())
{
getline(file,line);
if ((offset = line.find(search, 0)) != string::npos) {
cout << "found '" << search << endl;
}
}
file.close();
}
else
cout<<"file can not be open."<<endl;

return 0;
}
