What is the use of getch(); in the end of c 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....
