Getch & Enum

 Getch () is a way to get a user inputted character.It can be used to hold program execution, but the ‘holding’ is simply a side-effect of its primary purpose which is to wait until the user enters a character.

Getch();

 

Example of getch()

#include<iostream.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getch();

            cout<<"C=" <<c;

getch();

} 

Output

        press a output is c=a

Example of getch()

#include<iostream.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            cin>>c;

            cout<<"C=" <<c;

getch();

}

Output

        s -> enter

        C=s

Getche() 

Like getch() this is also non-standard function present in coini.h. It reads a single character from the keyword and display immediately on output screen without waiting for enter key.

 

Example of getche()

#include<iostream.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getche();

            cout<<"\nC=" <<c;

getch();

}

Output

        b

        C=b

Getchar() 

It read from standard input. It is not display immediately on output screen waiting for enter key.

Example of getchar()

#include<iostream.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getchar();

            cout<<"C=" <<c;

getch();

}

Output

        k -> enter

        C=k

Enum 

 

enum is a user defined data type in c.It is mainly used to assign names to integral constants, the names make a program easy to read and maintain.The keyword ‘enum’ is used to declare new enumeration types in c and c++.

            Enum day;

 

Example of enum 

#include<iostream.h>

#include<conio.h>

enum OS{

            mac=11,solaris=22,linux,kali,ubuntu,andriod

};

void main(){

            clrscr();

            cout<<"Mac=" <<mac;

            cout<<"\nSolaris=",solaris;

            cout<<"\nLinux=" <<linux;

            cout<<"\nKali=" <<kali;

            cout<<"\nUbuntu=" <<ubuntu;

            cout<<"\nAndriod=" <<andriod;

getch();

} 

Output

        Mac=11

        Solaris=22

        Linux=23

        Kali=24

        Ubuntu=25

        Andriod=26
