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 = 0b11111 << 10; // 0b00000000000000000111110000000000
    uint32_t value = reg & mask;

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

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