:evil: The following C program is mainly written to work as an address book. I have written the code but the VC++ compiler shows four errors and I cant find them :rolleyes: . Can some one please help me find them..my assignment deadline line is on the 10th of this month.

The list of things you've done wrong is too long for me to go into detail, so here are the biggies:

1) gets is wrong
2) main should not be called recursively
3) feof is not meant to be a loop condition
4) Your constructs are very inconsistent

At least you didn't use void main. Here is the code that compiles:

//initializing the header files

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

//defining the properties of the fields used in the program

#define NAME 50
#define ADDRESS 8
#define PHONE 20
#define EMAIL 20
#define SIZE 500

//declaring the functions

void Insert();
void Del_info();
void Display();
void Search();
void Exit();

char info[SIZE];

//using structures that represent the fields in the program

struct addressbook

  char name [NAME] ;
  char address [ADDRESS];
