23. Set Baud Rate Field in Control Register

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

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    uint32_t res = 0;
    // printf("temp val %d\n", ((baud&0xF)<<8));
    reg &= ~(0xF00);
    res = reg | ((baud&0xF)<<8);
    return res;
}

int main() {
    uint32_t reg;
    uint8_t baud;
    scanf("%u %hhu", &reg, &baud);
    printf("%u", set_baud_rate(reg, baud));
    return 0;
