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 field_bits = reg & (0x1F << 10);
    field_bits >>= 10;
    reg &= ~(0x1F << 10);
    if (field_bits < 31) {
        field_bits += 1;
    }
    reg |=  (field_bits << 10);
    return reg;
}

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