Set Baud Rate Field in Control Register

Code

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

uint32_t set_baud_rate(uint32_t reg, uint8_t baud) {
    // Your code here
    // uint32_t reg1 = 0xFFFFF0FF;
    // reg &= reg1;
    // reg |= (baud<<8);
    // return reg;
    uint32_t mask;
    mask = (((1<<4)-1)<<8);
    reg &= ~mask;
    reg |= (baud<<8);
    return reg;
}

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