Extract and Modify Field in a 32-bit Register

Code

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

uint32_t update_register(uint32_t reg) {

    uint32_t mask = ((1 << 5) - 1) << 10;
    uint32_t val;

    val = (reg & mask)>>10;
    //Clear the reg value
    reg &= ~(mask);
    if(val < 31)
    {
        val+=1;
    }
    reg |= (val<<10);

    // Your logic here
    return reg;
}

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