Experts answer:printf ( "Please select:"); a = getchar (); printf ( "1 * n"); replaced printf ( "Please select:"); a = getchar (); getchar (); printf ( "1 * n "); because you enter a characterAfter also entered a carriage return, you must also read out this carriage. getchar () function after you type a character on the screen display the characters, and wait for the end, after you type carriage return input. getch () function not show your input, do not wait for carriage return. In addition the statement is available intaTo, and does not have to change the char.
