Use VC ++ to write the Console
Program All day, black paper white screen, feel very depressed? Many people want to use some functions in conio. h/graphics. h, but they find that VC ++ does not have these header files. Of course, conio. h/graphics. H is the proprietary header file of Borland TC/BC, so these files are not found in VC ++. Copy the two header files and then use ?? Of course, the answer is no.

Given two positive integers m, n (m> = n !), Split m into N numbers and add M = A (1) + a (2) +... + a (n) to satisfy the following conditions: A (1) Compile and list all split methods.For example, if M = 7, n = 3, there is only one split method:7 = 1 + 2 + 4
Analysis:Int A, B;A = M/N; B = m % N;1: WHEN n is less than 4N = 2: can be divided into A-1, A + B + 1N = 3: A-1, A, A + B + 1;2: WHEN n is greater than 4In this case, we can prove a> N (using mathematical induction)In this case, M = a + A

Header file: conio. h
Function purpose: Read a character from the console
Function prototype: int getch (void)
Returned value: read characters
For example:
Char ch; or Int ch;
Getch (); or CH = getch ();
Use getch (); wait for you to press any key, and then continue to execute the following statement;
Use CH = getch (); after you press any key, assign the ASCII code corresponding to the

Programming specifications:
Almost all programming languages provide database functions to access the parallel port. For example, Borland C provides the "inportb" and "outportb" functions to read or write the IO ing addresses of external devices. This tutorial provides examples of VC, but it is easy to transplant to other compilers such as Borland C and TC. VB does not directly provide an access function for the parall

3. getchar () can be a string of characters, but only the first character is returned.Eg:
# Include
Int main () {char ch; ch = getchar (); printf ("the input character is: % c", ch); return 0 ;}
After running the preceding example, enter abc and press Enter. The value of ch is only a, and only a is displayed on the screen.
4. gets () input a string to the character array from the terminal and obtain a function value. The function value is the starting address o

Implementation of kbhit () in Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. We know that there is a keyboard test function in windows, int kbhit (void ). To use this function, you must include the header file conio. h. During execution, kbhit tests whether a keyboard is pressed. If yes, a non-zero value is returned. Otherwise, zero is returned.
In Unix/Linux, this function is not p

void * va_list;
Va_start (AP, parmn) is used for initialization. The AP points to the first parameter of a variable parameter.
The AP type is va_list.
Parmn is a fixed parameter before a variable parameter.
Va_arg (AP, type) obtains the parameters that the current AP points to, and points the AP to the next parameter of a variable parameter.
Type is the type of the parameter to be obtained.
The va_end (AP) end variable parameter is obtained.

Turbo C 2.0 found that many friends downloaded the file, but many people downloaded the file but did not configure it. The result was that it was not usable. To familiarize those who have just started to learn C language with the Turbo C 2.0 development environment as soon as possible, I have excerpted this article from the Internet for your reference. I hope it will be helpful.
