26. Extract and Modify Field in a 32-bit Register

#include <stdio.h>
#include <stdint.h>

uint32_t update_register(uint32_t reg) {
     uint32_t field;

    // Extract bits 10–14
    field = (reg >> 10) & 0x1F;

    // Increment if less than 31
    if (field < 31)
    {
        field++;
    }

    // Clear bits 10–14
    reg = reg & ~(0x1F << 10);

    // Write updated field back
    reg = reg | (field << 10);

    return reg;
    
}

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