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

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

int main() {
    uint32_t reg;
    scanf("%u", &reg);          // DECIMAL input

    uint32_t field = (reg >> 10) & 0x1F;  // Extract bits 10–14

    if (field < 31) {
        field++;
    }

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

    printf("%u", reg);          // DECIMAL output
    return 0;
}
