This error is self-explanatory:declaration missing ;
You need search your code for missing semicolon at the end of line.
Please, read the error message to the end to find out which line causes such of error.
Quote:void Book :: main()
{
void main_menu()
{
This is not valid
C++you cannot define a function inside another function definition (only lambdas are allowed).
I suggest you to use a more updated compiler (and learn a bit more ofOOPand modernC++).
someone please help me with this library project work or could someone send a 500 lines library management program. it must be simple like this program. it must only include struct, cout, cin, if, for, and stuff like that. you know what I mean ri8?
What I have tried:
#include<iostream.h>
#include<conio.h>
#include<string.h>
#include<stdio.h>
#include<dos.h>
static int bookcount=0;

This error is self-explanatory:declaration missing ;
You need search your code for missing semicolon at the end of line.
Please, read the error message to the end to find out which line causes such of error.
Quote:void Book :: main()
{
void main_menu()
{
This is not valid
C++you cannot define a function inside another function definition (only lambdas are allowed).
I suggest you to use a more updated compiler (and learn a bit more ofOOPand modernC++).
