Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint32_t bfield = (reg & 0x00007C00) >> 10;
    //printf("%u", bfield);
    if(bfield < 31)
    {
        bfield += 1; 
        reg &= ~(((1U << 5)-1)<<10);
        reg |= (bfield << 10);
    }
    return reg;
}

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