Hello. I thought I was done with this program but It doesn't work like its supposed to. I wrote the program to display the file every time I press one. But it only works the first time. After that it jus keeps sayin cannot open file. Why does it say that? Its just supposed to run the function again!! I have no errors or warnings on my compiler. Please can u take a look at this and tell me what's wrong!! I have another question how do you perform a search in a file for a char variable. Like searching a contact name. is it possible? Thats' it. here is the code.
#include<iostream>
#include<iomanip>
#include<cmath>
#include<cstdlib>

//Funtion prototypes

void Delete();
int Create();
void Modify();
int Search();
void Quit(void);
void Restart(int);
