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 val = ((1 << 5)-1) << 10;
    int tem =  ((val & reg) >> 10);

    if(tem < 31)
        tem += 1;

    reg &= ~val;
    return reg |= (tem << 10) & val;
}

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