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 temp = 0;
    temp = ((reg >> 10) & 0x1F);

    if(temp < 31){

        reg &= ~(0x1F) << 10;
        reg |= (((temp + 1) & 0x1F) << 10);

    }

    return reg;
}

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