1: What does c language mean?

C language is a process-oriented, abstract general-purpose programming language that is widely used Developed at the bottom. C language can compile and process low-level memory in a simple way. C language is a high-efficiency programming language that only generates a small amount of machine language and can run without any operating environment support. Although the C language provides many low-level processing functions, it still maintains cross-platform characteristics. C language programs written in a standard specification can be used on many computer platforms, including some operating platforms such as embedded processors and supercomputers. to compile.

2. Integrated development environment

Code::Blocks, open source and free C/C IDE

3: c language program

The following is a standard output device (stdout) Above, a simple program that prints the "Hello, world!" string. A similar program is usually used as the first program when learning a programming language:

#include <stdio.h>
int main（）
{
printf（"Hello, World! \n"）；
return 0;
}

Example analysis:

The first line of the program #include ade979de5fc0e1ca0540f360a64c230b is a preprocessor instruction , tells the C compiler to include the stdio.h file before actually compiling.

The next line int main() is the main function, and the program execution starts from here.

The next line printf(…) is another function available in C and will display the message "Hello, World!" on the screen.

The next line return 0; terminates the main() function and returns the value 0.
