C language is a general-purpose computer programming language with a wide range of applications. The design goal of C language is to provide a programming language that can compile and process low-level memory in a simple manner, generate a small amount of machine code, and can run without any operating environment support. C++ is an object-oriented programming language developed on the basis of C language, which is widely used. C++ supports multiple programming paradigms-object-oriented programming, generic programming and procedural programming.
Objective-c – type instead of insertion characters between variables, enclose in parentheses
I am reading Apple’s documentation and I saw something similar (void(^)(void)). Can someone explain the meaning of this sentence? ^It’s XOR, right? Void XOR Void does not make much sense to me?
Run a program containing multiple source files in the GNU C compiler
I use DEV GNU c compiler on Windows 7 operating system. I need to know how to compile a program with multiple source files.
This is an example,

C – How to use glortho () in OpenGL?
I can’t understand the usage of glOrtho. Can someone explain its usage?
Is it used to set the limits of x, y and z coordinates?
glOrtho(-1.0, 1.0, -1.0, 1.0, -1.0, 1.0); This means that
Why SCANF must use the address of the operator
As the title says, I always want to know why scanf must take the address of the operator (&). Because C has only “pass-by-value” parameters, to pass a’variable’ to put a value, you must pass its
PRINTF parameter is insufficient
My question is about the behavior after printf with missing parameters:
printf(“%s blah blah %d “, int); // integer was given as argument (and not int written) I already know that if the form
Understand concurrent file writing from multiple processes
From here: Is file append atomic in UNIX
Consider the situation where multiple processes open the same file and append to it. O_APPEND guarantees that the file is found The write operation at
Use pointer to write and read structures
I am working on a mailbox project, and I have these two structures:
struct mmbox_mail
struct mmbox_mail {
char *sender, *recipient;
char *obj, *date;
char flags;
size_t size;
};
