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
    uint16_t r=reg&(0x7C00);
    r=r>>10;
    if(r<0x1F){
        r+=0x01;
        reg=reg&((~0u)<<15|(1<<10)-1);
        reg=reg|(r<<10);
    }

    return reg;
}

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