There are two ways to define constants in C #, one called Static constants (Compile-time constant) and the other is called Dynamic constants (Runtime constant). The former is defined by "const", which is defined by "ReadOnly". For static constants

Interview often encounter problems, C language implementation string reverse. such as input "ABCD", Output "DCBA". Recently tidied up, the following code has been tested. #define Max 200 main() { 　　　char str[Max]; 　　　printf("请输入字符串:"); 　　　gets(str)

Shared memory is the lowest communication mechanism and the fastest communication mechanism in LUnix system. Shared memory uses two or more processes to share the same block of memory to achieve interprocess communication. Typically, a process

A Problems with fonts in the C language There are two ways of displaying in C language, that is, text mode and graphic mode. As I know, fonts can only be controlled in graphic mode. Let's take a look at some of the fonts defined in C Name index
