One of the most common CRT decisions developers face is how to link it.
If you link one DLL with static CRT (/MT) and another with dynamic CRT (/MD), they will have separate heaps. Allocating memory in one module and freeing it in another causes crashes. Rule: All modules in a process must use the same CRT linking model.
At its core, the C Runtime Library is a collection of pre-written code that handles the basic operations required by programs written in C and C++.
When a developer writes printf("Hello World");, the compiler does not generate raw machine code to parse the format string, manage the console buffer, and output characters. Instead, it inserts a call to a function inside the CRT. The CRT then executes the complex, platform-specific instructions needed to make that text appear on the screen.
The CRT code is copied directly into your .exe or .dll file.
