Bit Operations using Macros

Code

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

uint8_t set_bit(uint8_t reg, uint8_t pos) {
    return reg | (1 << pos);
}

uint8_t clear_bit(uint8_t reg, uint8_t pos) {
    return reg & ~(1 << pos);
}

uint8_t toggle_bit(uint8_t reg, uint8_t pos) {
    return reg ^ (1 << pos);
}

uint8_t modify_register(uint8_t reg) {
    reg = set_bit(reg,2);
    reg = set_bit(reg,7);
    reg = clear_bit(reg,3);
    reg = toggle_bit(reg,5);
    return reg;
}

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