C does not contain strings. It must be implemented using char *. # Include # include "base. H "const char base [] =" character +/= "; char * base64_encode (const char * data, int data_len) {// int data_len = strlen (data ); int prepare = 0; int

I have always had many questions about the Assembly codes generated by CLR instant compilation. In many cases, they are not optimized as Microsoft claims, especially because they are not inline ). I once guessed that it was less optimized for IDE

I learned the Objective C of stm32 and interrupted nesting to share with you! Because stm32 has 43 interrupt sources, when multiple interruptions are used at the same time, the priority of the interruption must be specified. Objective C is the

Summary three methods of using "new" in C ++ Although there are three kinds of new usage, there are still two categories. Which two types are there? One is new operator, also called new expression; the other is Operator new, also called New operator.

Fputs Int fputs (const char * STR, file * stream ); Write string to stream Writes the string pointedStrToStream.The function begins copying from the address specified (Str) Until it reaches the terminating null character ('/0'). This final

When beginners are Learning Object-oriented programming languages, they have more or less questions. The code we write is quite different from the code that is finally compiled and translated, we don't know what the compiler does in the background.
