Validate Configuration Register Layout

Code

#include <stdio.h>

typedef struct {
    unsigned short reg;
} ConfigRegister;

int validate_config(ConfigRegister *cfg) {
    // Write logic using pointer access
    if(((cfg->reg)&1==1)&&(((cfg->reg)>>2&0x3)!=0x03)&&(cfg->reg>>4==0))
    
    {
        return 1;
    }
    return 0;

}

int main() {
    ConfigRegister cfg;
    scanf("%hx", &cfg.reg);

    int result = validate_config(&cfg);
    printf("%d", result);

    return 0;
}
