Getch & Enum

Getch() 

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<stdio.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getch();

            printf("C=%c",c);

getch();

}

Output

        press a output is c=a

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<stdio.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getche();

            printf("\nC=%c",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<stdio.h>

#include<conio.h>

void main(){

            char c;

            clrscr();

            c=getchar();

            printf("C=%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<stdio.h>

#include<conio.h>

enum OS{

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

};             

void main(){

            clrscr();

            printf("Mac=%d",mac);

            printf("\nSolaris=%d",solaris);

            printf("\nLinux=%d",linux);

            printf("\nKali=%d",kali);

            printf("\nUbuntu=%d",ubuntu);

            printf("\nAndriod=%d",andriod);

getch();

}

Output

        Mac=11

        Solaris=22

        Linux=23

        Kali=24

        Ubuntu=25

        Andriod=26
