What is the usage of the limit function in the C programming language?

In the C language, “limit” is not a built-in keyword or function. Therefore, it cannot be directly used to restrict any content.

However, there are some functions and macros related to limitations in the C language, as shown below:

1. INT_MAX and INT_MIN: These are macros defined in the header file that represent the maximum and minimum values of the int data type.
2. CHAR_BIT: It is a macro defined in the header file, representing the number of bits in a char type.
3. Array length: In C language, arrays can be used to limit the number of elements of the same type in a group. For example, int arr[10] defines an array containing 10 integers.
4. The #define preprocessing directive allows for the definition of custom symbolic constants to limit the range of variables.

These are some common usage related to restrictions in the C language. However, the specific usage depends on your needs and context.
