Assignment of character Arrays

 

1: Define character arrays in struct and assign values

First look at a piece of wrongCode

Struct stype {
Char c1 [16]
};

Struct stype S1;
S1.c1 = "hello"; // Error

This is a naive concept error. Char c2 [10] declares an array of 10 elements C2. At this time, C2 space has been allocated. C2 is the address of this array and is a constant, if C2 = "hello" is performed again, the system tries to change C2. This is wrong.

Strcpy (s1.c1, "hello"); // This is correct

 

The following is a better solution:

Struct stype {
Char c1 [16]
} S1 = {"hello"}; // not only space is allocated to S1, but an initial value is also set for S1 members. You can view the c99 standard.
