I think this should work :

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

int main ()
{
      char Name[80], Search[80];
      int ID, flag = 0;
      FILE * pFile;

      scanf("%s", Name);
      pFile = fopen ("myfile.txt","r");    // Enter your file-name instead of myfile.txt
      while( !feof(pFile) )
      {
            fscanf (pFile, "%s %d", Search, ID);
            if( ! strcmp(Name, Search) )
            {
                  flag = 1;
                  break;
            }
      }
      fclose (pFile);
      if( flag )      printf ("The name %s was found in the file !!\n", Name);
      else            printf ("The name %s was NOT found in the file !!\n", Name);
      return 0;
}

[SaswatPadhi]

That should be simple enough :

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

int main ()
{
      char Name[80], Search[80];
      int ID, flag = 0;
      FILE * pFile;

      scanf("%s", Name);
      pFile = fopen ("myfile.txt","r");    // Enter your file-name instead of myfile.txt
      while( !feof(pFile) )
      {
            fscanf (pFile, "%s %d", Search, ID);
            if( ! strcmp(Name, Search) )
            {
                  flag = 1;
                  break;
            }
      }
      fclose (pFile);
      if( flag )      printf ("The name %s was found in\n%s %d\n", Name, Name, ID);
      else            printf ("The name %s was NOT found in the file !!\n", Name);
      return 0;
}

thank you

so,

how I can conut the name

I mean

if I use switsh like this
1- search
2- count nume

how I count the nume ( which is the code for this )

[SaswatPadhi]

I have three things to say:
(1) Don't be in a hurry ! Take your time and post without so many spelling error.
(2) Could you explain what exactly do you mean by count ? May be give an example.

(3) This website is not for providing free home-work help. Please tell us where you are stuck, and we would help. Don't ask us for complete source code.

[telfer]

I am sorry

may be I have some error and I ask you more , but I want to know only

count mean ( how many name in this file )

if you want to answer this , thank you for ever

[SaswatPadhi]

You can ask as many times and as many questions as you want, but please do try yourself first and then ask us. It will be beneficial for you only.

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

int main ()
{
      char Name[80], Search[80];
      int Count = 0;
      int ID, IDSearch, flag = 0;
      FILE * pFile;

      scanf("%s", Name);
      pFile = fopen ("myfile.txt","r");    // Enter your file-name instead of myfile.txt
      while( !feof(pFile) )
      {
            fscanf (pFile, "%s %d", Search, IDSearch);
            ++ Count;
            if( ! strcmp(Name, Search) )
            {
                  flag = 1;
                  ID = IDSearch;
            }
      }
      fclose (pFile);
      printf("Total %d names found in the file.\n", Count);
      if( flag )      printf ("The name %s was found in\n%s %d\n", Name, Name, ID);
      else            printf ("The name %s was NOT found in the file !!\n", Name);
      return 0;
}

All these 3 were very easy. Are you beginning to learn C/C++ ?
