Why should I not use #include<stdio.h> #include<conio.h> void main

Question

Please explain it

Answer 1

@Ashutosh Upadhyay
Yes as conio.h is not there in sololearn's library files...
Thus you will have to use cin.get() instead of getch(), etc...

Also, stdio.h may work and if it doesn't , try using cstdio instead, like this:

#include<cstdio>

So, on SoloLearn,you cannot use conio.h as it simply isn't there...

Answer 3

@Anubhav Pandey
But, thanks to SoloLearn's 'wonderful' Interface, Sleep does not do anything here.
Rather, the program's output takes more time to load.
It is just like inputs...

Answer 4

As they are simply C headers and functions...
If you're using C++, why use them?
We have better things in C++...
//iostream, cin.get(), cout

Answer 7

A messaging app?
Web languages would be easier to use in this, as C++ can store messages and connect to other programs via the internet, but I don't know how to implement those features...

But a chat system may be possible in c++, but one will have to use 3rd party libraries for that...

But html, css etc will give you a larger scope for this task, as they have functions to easily handle such things...

Answer 8

@Anubhav
system("cls") for windows,
system("clear") for linux and android...

//Need cstdlib for these...

Answer 13

printf and scanf functions are included in studio.h and getch () is included in conio.h
so if u don't use them than compiler will unable to understand the meaning of such function and it will return error
