Set Baud Rate Field in Control Register

Code

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

uint32_t set_baud_rate(uint32_t reg, uint8_t val) {
    // Your code here
        uint32_t mask=0,mask2=0;
    for(int i=8;i<(8+4);i++){
        if((val&1))
            mask|=(1<<i);
        else
            mask2|=(1<<i);
        val>>=1;
    }
    reg&=~mask2;
    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;
}
