Tuesday, Wednesday, and so on as the integral constants. If you do not assign any value to the enum constant, then const1 will be 0, const2 will be 1, and so on. You can also define other variables with this enum data type as mentioned in the program: ...
（1） Pointer functionThe pointer function returns pointer type data.The following example points to the first character of a string using the char type, and the string ends at 0. Knowing the first letter can tell the entire string.（二）函数指针指针函数：int *p()函数指针：int (*p)()（...
This program reads the user’s entered number from the keyboard, prompts them to enter a number, and then writes it back on the screen. Let’s now look at some of the most used output routines. getchar() –A single character can be read from the keyboard using the getchar function....

Program Adjustments Did the output for this program briefly flash onscreen and then disappear even though you added the following line to the program, as described in Chapter 2, “Introducing C”? getchar(); For this example, you need to use that function call twice: getchar(); getchar(...
