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 field_mask = (((1U << 5)-1) << 10);
    uint8_t field = (reg & field_mask) >> 10;

    if(field < 31) field++;

    reg &= ~field_mask;
    reg |= ((uint32_t)field << 10);

    return reg;
}

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