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 bit_field = 0;
    uint32_t mask = (0x1F << 10);

    bit_field = ((reg & mask) >> 10);

    if(bit_field < 31) bit_field += 1;
    
    reg &= ~mask;
    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;
}
