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 a=((reg>>10&((1U<<5)-1)));
    if(a<31){
        a=a+1;
    }
    reg=(reg&~(((1U<<5)-1)<<10))|a<<10;
    return reg;
}

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