Introduction to getch() function on C programming

On C programming language, there is a function named getch() function, its sintax writing as follows:

getch();

this getch actually is abbreviation of getcharacter.

What are using of getch function?

• Stop a ongoing process
• Read input from keyboard. Character is gotten from keyboard only one character

Example:

• Open C program
• Create a new file, and save the file
• Type main(){}
• Menu Execute > Compile
• After compile is done (success), Menu Execute > Run, then Run result will not be seen, only seen a black window for a moment and close again immediately

Now try to add getch(); in curly braces of main(), so that program sintax be:

main(){ getch(); }

Now try to do again:

• Menu Execute > Compile
• Menu Execute > Run

Hm, now has been seen its run result, it is a blank page. Now try to type one character, then run result window will close immediately. Approsimately function of getch()
