Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) 
{
    uint32_t result;
    result=(reg&0x00007c00)>>10;
    if(result<31)
    {
        result++;
    }
    else if(result==31)
    {
        return reg;
    }
    reg=reg&0xffff83ff;
    reg=reg|(result<<10);
    return reg;
}

int main() {
    uint32_t reg;
    scanf("%u", &reg);
    uint32_t updated = update_register(reg);
    printf("%u", updated);
    return 0;
}
