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) {
    for(int i=8,j=0;i<12;i++,j++)

        if(baud & (1<<j))
        reg |= (1<<i);
        else
        reg &= ~(1<<i);
    }
    return reg;
}

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