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 tmp = (reg & (((1U << 5) - 1) << 10));
    tmp = tmp >> 10;
    tmp = (tmp >= 31) ? tmp : (tmp + 1);
    reg = (reg & ~(((1U << 5) - 1) << 10)) | (tmp << 10);
    return reg;
}

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