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
    //get field val 
    uint8_t val = (uint8_t)((reg>>10)&0b11111);
    if (val<31){
        val++;
        reg &= ~(0b111110000000000);
        reg |= (val<<10);
    }
    return reg;
}

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