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) {
   int pos=8,len=4;
   uint32_t bit=0;
   for(int i=0;i<len;i++){
    bit=bit|(1<<i);
   }
   bit=bit<<pos;
   bit=~bit;
   reg=reg&bit;
   uint32_t val=baud;
   val=val<<pos;
    return reg|val;
}

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