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 temp=0;
    uint32_t cnt=0;
    while (cnt<5){
        if ((reg>>(10+cnt))&1){
            temp|=(1<<cnt);
            
        }
        cnt++;
    }

    if (temp<31) temp++;

    reg&=(0xFFFF83FF);
    reg|=(temp<<10);
    return reg;


}

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