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 mask = ((0x1F << 10) & reg)>> 10;
    if(mask < 31){
        mask += 1;
    }
    else{
//
    }
   reg &= ~(0x1F << 10) ;

    reg |= (mask << 10);
    return reg;
}

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