getch(); is used for unbuffered input. e.x:
int main()
{
char num=0;
printf("Press a keyboard button: ");
num = getch(); //This brings in 1 character that the user pressed on the keyboard
printf("\nYou pressed: %c", num); //This prints the character you pressed
getchar(); // I am using getchar(); to stop the program from ending after pressing buttons
return 0;
}
My input will be within the ().
output:
Press a keyboard button: (v)
You pressed: v
EOP //End of program
I hope this has helped you!

Difference in using a method that return value and method that does not return value in object orinted programming?
A method that return a value should have a return statement. The method signature should indicate the type of return value. While in the case of a method that does not return a value should not have a return statement and in the signature, the return type is void. When using a method that doesn't return a value, a programmer can not get a value from that function, but instead, it can only change variable values and run other methods.
