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;
   uint32_t check= (reg &mask)>>10;
   if(check<31)
   {
    check=check+1;
   }
   reg&=~(mask);
   reg|=(check<<10);
   
    return reg;
}

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