Extract and Modify Field in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>

uint32_t update_register(uint32_t reg) {
    uint8_t value =  (reg >> 10 ) & 0x1F; 
    if(value <31){
        value +=1 ; 
        reg &= ~(0x1f<< 10)  ;
        reg |= (value << 10 )  ;
    }  
   return reg ; 
}

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