Validate Configuration Register Layout

Code

#include <stdio.h>

typedef struct {
    unsigned short reg;
} ConfigRegister;

int validate_config(ConfigRegister *cfg) {
    // Write logic using pointer access
    int cond1 = 0, cond2 = 0, cond3 = 0;

    cond1 = cfg->reg & 0x1;
    cond2 = ((cfg->reg >> 2) ^ 0x11);
    cond3 = cfg->reg >> 4;

    if(cond1 && cond2 && !cond3)
        return 1;
    else
        return 0;
}

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

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

    return 0;
}
