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 config;

    // 1. Extract the bits
    config = (reg >> 10) & 0x1F;

    // 2. Increment
    if(config < 31) config += 1;

    // 3. Set
    // (i) Clear
    reg &= ~(0x1F << 10);
    // (ii) Set
    reg |= (config << 10);

    return reg;
}

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