Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>
uint8_t modify_register(uint8_t reg) {
    reg |= (1 << 2);
    reg |= (1 << 7);     
    reg &= ~(1 << 3);   
    reg ^= (1 << 5);  
    return reg;
}
int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
