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 mask;
    //first clear the old baud value 
    reg=reg&~(((1<<4)-1)<<8);
    //create the mask by adding baud value to the mask 
    mask=(baud&(0x0F))<<8;
    //set the reg value by oring . 
    reg=reg|mask;
    return reg;
}

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