Struct Padding

Code

#include <stdio.h>
#include <stdint.h>

typedef struct {
    char a;
    int b;
    short c;
} MyStruct;

void print_offsets() {
    MyStruct s;
    uint8_t *p2s ,*p2a ,*p2b ,*p2c;

    p2s = (uint8_t *) & s; 
    p2a = (uint8_t *) & s.a;
    p2b = (uint8_t *) & s.b;
    p2c = (uint8_t *) & s.c;

    printf("Offset of a: %u\n",(p2a - p2s));
    printf("Offset of b: %u\n",(p2b - p2s));
    printf("Offset of c: %u\n",(p2c - p2s));
    printf("Size: %d",sizeof(s));
    

}

int main() {
    print_offsets();
    return 0;
}
