Extract and Modify Field in a 32-bit Register

Code

#include <stdio.h>
#include <stdint.h>
#define mask (((1<<5)-1)<<10)
uint32_t update_register(uint32_t reg) {
    // Your logic here
    uint8_t val = (reg&mask)>>10;
    //printf("reg_val %x\tVal :%x\n",reg,val);
    if(val<31) 
    {
        
    reg = ((reg &~mask)|(++val<<10));
    }
    return reg;
}

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