Initializing Structure Members to Zero in C Language

In C language, to initialize the members of a structure to 0, you can use curly braces {} for initialization. The inside of the braces can be left empty, so the compiler will initialize all members of the structure to 0 (for numeric types) or a null character (for character types). For example:

#include <string.h>

struct Student {
    char name[50];
    int age;
    float score;
};

int main() {
    struct Student student1 = {0}; // All members initialized to 0 or null character
    return 0;
}

Alternatively, you can use the memset function to set all members of the structure to 0:

#include <string.h>

struct Student {
    char name[50];
    int age;
    float score;
};

int main() {
    struct Student student1;
    memset(&student1, 0, sizeof(student1)); // Set all members of the structure to 0
    return 0;
}

Both of these methods can initialize all members of the structure to 0.
