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 r =0 ;
    uint32_t x = baud << 8;
    for(int i = 0; i < 4;i++){
        r = r |(1<<i);
    }
    reg = reg & (~(r << 8)); 
    return reg | x;
}

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