i want to run normal program with class type of program

[LedArts]

NEED HELP
Can i run "class" code with normal example code.
i try but only one of them is running. what should i do please tell me.

class example
class colorWipe: public animation {
public:
colorWipe(void) { w = random(256); }
virtual void init(void);
virtual void show(void);
private:
byte w;
int index;
bool fwd;
};

void colorWipe::init(void) {
int p = random(2, 4);
w += p*16 + 1;
fwd = random(2);
index = 0;
if (!fwd) index = strip.numPixels() - 1;
}

void colorWipe::show(void) {
uint32_t color = Wheel(w);
if (fwd) {
if (index > int(strip.numPixels())) { // Start new sequence with the new color
init();
complete = true;
return;
}
strip.setPixelColor(index++, color);
} else {
if (index < 0) { // Start new sequence with the new color
init();
complete = true;
return;
}
strip.setPixelColor(index--, color);
}
complete = false;
}

Normal example
void theaterChase(uint32_t c, uint8_t wait) {
for (int j=0; j<10; j++) { //do 10 cycles of chasing
for (int q=0; q < 3; q++) {
for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
strip.setPixelColor(i+q, c); //turn every third pixel on
}
strip.show();

  delay(wait);

  for (uint16_t i=0; i < strip.numPixels(); i=i+3) {
    strip.setPixelColor(i+q, 0);        //turn every third pixel off
  }
}

}
}

only mgr.show is running in this loop
void loop() {
mgr.show();
theaterChase(strip.Color(127, 127, 127), 50); // White
theaterChase(strip.Color(127, 0, 0), 50); // Red
theaterChase(strip.Color(0, 0, 127), 50); // Blue
}
what should i do please tell me.
