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 mask = 0x1F << 10;
    uint32_t reg1 = (reg & mask) >> 10;

    if((reg1 ) < 0x1F){
        reg1 += 1;
        reg &= ~mask;
        reg |= (reg1 << 10);
    }
    return reg;
}

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