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 = (reg >> 10u) & 0x1F; // Get current field value
    if(field < 31) {
        field++;
    }
    reg &= ~(0x1F << 10); // Clear field in reg
    reg |= field << 10; // Set field in reg
    return reg;
}

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