getch() is used to hold the console(output) window on the screen after the whole program run is completed till the user enters a key from keyboard. However, the character entered is not displayed on screen. For that you will have to use getche() function. Both functions are present in conio.h header...

getch() is used to hold the screen.It makes sure that you can see your output on the output screen.If you don't use getch() at the end of your c program then you won't be able to see the output of your program.

This function is used to get a character from your console like scanf.. Reason for using @ end of every program: normally your c program executes line by line. Your console window(where we see our output) will appear of scanf to get our input values.. also for writng our output in printf console willopen. See the console will not wait and show the final result(after executing final line of code). It completed or executed all the lines of code , so it will terminated. So if you are using this getch() at end of code, the console window will wait for getting input from you. So tht we can check the final ouput(provided you added getch at last line). Instead just use scanf() to read any value, thepurpose is to make console open untill we wish to close. Hope it helps..! read less

Most of the c program end with this statement. So most of the people thought that this program is used to get output on the screen. But it is wrong This statement is used to read a single character from console without an echo to screen.. let see how it is.... When you run this program using turbo c++ compiler we cannot see the output. Actually the out put was already printed on the screen , at the printing time itself the run window will close. When you go to the user screen (window --> user screen) , you can always see what the last status of program running. Here getch() helps to the user for waiting to enter a character from keyboard .. read less

getch() is to get character. It waits to get a character in input from console. So apparently it is used to hold the screen so you can see the output. This can be used anywhere you want to get any character input from console.

If you don't use getch , the control comes back to program editor window and we need to press alt+f5 to see output screen. To avoid this we use getch to make sure the program waits till you see result and press a key. It is not a good practice to use getch.
