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

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