Bit Operations using Macros

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

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    int se = (1<<2)+(1<<7);
    int cl = ~(1<<3);
    int to = 1<<5;
    reg = (((reg|se) & cl) ^ to);
    return reg;
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
