New improved Function for positive integer check

check_positive_corrected.cpp

// check if integer is greater than zero or not
// this function returns true when a!=0 ie if (a<0 || a>0)
// this is not a good check for positive integers
// I realize this is not a good example - but for the sake of argument
bool check_if_positive(int a){
  if(a>0){
    return true;
  }
  else{
    return false;
  }
}
