Extract and Modify Field in a 32-bit Register

Code

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

#define EXTRACT_POS         10
#define EXTRACT_SIZE        5
#define EXTARCT_MASK        (1 << EXTRACT_SIZE) - 1
static int temp = 0;

uint32_t update_register(uint32_t reg) {
    // Your logic here
    for(int i=0; i < EXTRACT_SIZE; i++)
    {
        temp |= (((reg >> (EXTRACT_POS + i)) & 1) << i);
    }
    (temp < 31)?++temp:temp;
    reg &= ~(EXTARCT_MASK << EXTRACT_POS); //clear old reg values
    reg |= ((temp & EXTARCT_MASK) << EXTRACT_POS); //update new values
    
    return reg;
}

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