How can data be stored in binary form in the C language?

In the C language, a method of storing data in binary format is by using bitwise operators. Here are some commonly used bitwise operators:

1. Bitwise AND (&): Perform an AND operation on the corresponding bits of two numbers, with each resulting bit being either 0 or 1.
2. Bitwise OR (|): Perform a logical OR operation on corresponding bits of two numbers, with each resulting bit being either 0 or 1.
3. Bitwise XOR (^): performs an operation on each corresponding bit of two numbers, resulting in each bit being either 0 or 1, with a bit being 1 if the two bits are different and 0 if they are the same.
4. Bitwise negation (~): invert each bit of the operand.

By using these bitwise operators, data can be stored in binary form and manipulated accordingly. For example, the bitwise AND operator can be used to set a specific bit of an integer to 1, or the bitwise OR operator can be used to set a specific bit of an integer to 0.

Additionally, in the C language, one can also use bit fields to store data. Bit fields are a type of structure member that allows one to specify the number of bits for each member, enabling binary storage of data. For example:

struct {
    unsigned int flag1 : 1; // 1位
    unsigned int flag2 : 1; // 1位
    unsigned int flag3 : 1; // 1位
    unsigned int flag4 : 5; // 5位
} bits;

In the example above, a structure with 4 bit-field members is defined, each specifying a corresponding number of bits. This allows for binary storage of data using bit-fields.
