How to initialize and assign values to an array of structures in C programming language

There are two ways to initialize and assign values in a C language array of structures.

1. Assign values one by one: You can use the method of assigning values one by one to assign values to each element of a structure array, for example:

struct Student {
    char name[20];
    int age;
};

int main() {
    struct Student students[3];
    
    strcpy(students[0].name, "Tom");
    students[0].age = 18;
    
    strcpy(students[1].name, "Alice");
    students[1].age = 20;
    
    strcpy(students[2].name, "Bob");
    students[2].age = 19;
    
    return 0;
}

1. Initialization list can be used to initialize and assign values to a struct array, for example:

struct Student {
    char name[20];
    int age;
};

int main() {
    struct Student students[3] = {
        {"Tom", 18},
        {"Alice", 20},
        {"Bob", 19}
    };
    
    return 0;
}

Using the above two methods, it is possible to initialize and assign values to arrays of structures in the C language.
