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 i;
    int ex1, ex2;
    int j=0;
    for(i=8;i<=11;i++){
        ex1 = reg & (0x01<<i);
        ex2 = baud & (0x01<<j);
        j++;
        if(((ex1 != 0) && (ex2 != 0)) || ((ex1 == 0) && (ex2 == 0))) continue;
        else{
            if((ex1 != 0) && (ex2 == 0)) reg = reg & (~(0x01<<i));
            else reg |= 0x01<<i;
        }

    }
    return reg;
}

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