Code for custom Assert for throwing invalid_argument error and runtime_error error:-

#include<stdexcept>
#define custArgAssert(x,y) if(!x) throw std::invalid_argument(y);
#define custAssert(x,y) if(!(x)) throw std::runtime_error(y);

int main(){
  	custAssert(4==3, "4 is not equal to 3") // no ';' needed
  	return 0;
}

You can define more types of error in similar manner.
