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
    uint8_t bit_field = 0;
    bit_field = ((reg >> 10) & 0x1F);

    if (bit_field < 31) {

        bit_field ++;

        reg &= ~(0x1F << 10);

        reg |= bit_field << 10;

    }

    return reg;
}

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