Introduce: Why use dynamic memory allocation int a = 20;char arr[10] = {0}; Space opened up above: 1.Space development size is fixed. 2.When declaring an array, you must specify the length of the array, and the memory it needs is allocated at compile time. Sometimes the size of space we need is only known when the program is running (fo ...

1, Pointers and arrays 1. Ordinary pointer The pointer is the memory address where the variable is stored. It has a type, and the address has no type. int main(int argc, char const* argv[]) { //Define variables int i = 90; //Define pointer p and take address character for variable i int *p = &i; float fi = 0.8f; ...

Continuously allocate storage space for n variables 2. All variable data types must be the same 3. The byte size occupied by all variables must b ...

preface **This article introduces character functions and string functions, from 0 to proficient, how to reference to how to simulate the implementation. In C language, we often operate on strings, so we can call many library functions directly. However, if we want to deeply understand C language, we need to know how to realize its princip ...
