C Determine whether the elements in the two structures are exactly the same

understanding:
eg:
range
- 1. There is no problem in applying the structure in the test structure, and it can be judged;
- 2. The element in the test structure is a collection type, and the judgment is wrong (**~~cannot be used~~ **);
Solve the above problem: operator overloading

understanding:

In C, the structure can use = to assign a structure, but you cannot use == to judge two structures;
here the memcmp() function is used, the return value is int, and
its function is to combine the storage area buf1 and storage area buf2. The first n bytes are compared. This function compares in bytes, and size writes the length of the structure Insert picture description here

The background is still QT
