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 mask = 0x1F & (reg >> 10); 
    if (mask < 31){
        mask = mask + 1;
        reg = (reg & ~(0x1F << 10)) | (mask << 10);
        return reg;
    }
    return reg;
    
}

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