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 heee 
            uint32_t field;

                // Extract bits 10–14 (5 bits)
                    field = (reg >> 10) & 0x1F;

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

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

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

                                                            return reg;
                                                            }
    

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