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
    int mask=(1<<5)-1;
    int mask2=0;
    mask2=mask2 | reg;
    mask2=mask2>>10;
    int val=mask & mask2;
    if (val<31)
    {
        val++;
    }
    val=val<<10;
    mask=mask<<10;
    reg=reg & ~mask;
    reg =reg | val;

    return reg;
}

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