Problems with search in fail

[citrucc]

Hi all

I have some problems with searching in fail.

I have mass of structs and I need to find user's telephone number by his name.

Please tell me what I do wrong!!!

FILE *fp;
fp= fopen("info.dat","rb");
if (fp == NULL)
printf("Fail not open");
else
{
	char searchname[10];
	int fsize;
	bool r;

	fseek(fp,0,SEEK_END);
	fsize = ftell(fp);
I	int n = fsize / sizeof(infouser);
	infouser* infouser_mas = new infouser[n];
	fseek(fp,0,SEEK_SET);
	fread(infouser_mas,sizeof(infouser),n,fp);

	printf("Enter user name: ");
	cin.getline(searchname, 10);
	cin.get();

	for (int i = 0; i<n ; i++)
	{
		if ( strcmp (infouser_mas[i].name, searchname)==0)
		{
			cout << "\nUser name : " << infouser_mas[i].name <<" -> " << infouser_mas[i].telefonnumber << endl;		
			r=true;
		}	
	}
	if ( r == false)
	{

		cout << "No user found!";

	}
	fclose(fp);
}
