functioning of getch()

[roodiii]

Hi,

I have gone through he standard C program format. And It seems that each program must contain the getch() function. I am not getting exact use of the getch() function.
What will happens if program does't contains getch() function? If anybody know about the functioning of the getch() function then please let me know.

Hi friends,

Below are some information regarding the getch() function of the C programming:

1. When we use getch() function in program, then while execution of program this function will waits to take inputs from the program user.
2. "getch() function" gives control back to main() function of the program as soon as the user enters the any input for the program.
3. The basic use of getch() in the programming is to display the number or character which is inputted by the user.

Hi,

For your information, the getch() function in the C language is hired from library files using header file known as "#include<conio.h>". I hope you are aware that the use of input while execution of the program is as screen stopper. And to achieve this task "getch()" get used. If you don't include the "getch() function" in program code, then you are not able to see the input for the program. The getch() function loose the control after the any character input.

I hope this will help you understand the getch() function

Hi,

Please try to execute the following program which doesn't comprises the getch() function. Execute this below code and let's see what happens:

void main()
{

clrscr();

int a,b,c;

printf("Enter two numbers");
scanf("%d%d",&a,&b);

c= a+b;
printf("sum=%d", c);

}
