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 = 0;
    tmp = ((reg & (((1U << 5) - 1) << 10)) >> 10);
    if (tmp < 31) ++tmp;
    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;
}
