//underflow- going so small tht you cannot do it anymore and thenyou become positive //overlow-this is wwhen you are going so high, you go back to 0

int main () { float x = 1, y = 0.0001; cout << x << endl; x *=y' cout << x << endl;

//data type promotion - do not lose information you are being converted to something more powerful

int main () {

//double float int char bool 
//promotion and demotion 

int x = 2000000000; cout << x << endl; cout << (x * 2) << endl; cout << (int)(x * 2) << " (explicit cast) cout << ((int)(x * 2) << "

return 0'
}
