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
    unsigned int mask = (1 << 5) - 1;
    uint32_t value = (reg >> 10) & mask;
    if(value < 31)
    {
        value++;
    }
    unsigned int field_mask = ((1 << 5) - 1) << 10;
    reg &= ~field_mask;

    reg |= (value << 10);

    //printf("%d \n",value);
    return reg;
}

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