Bracket usage
When using brackets, always do

| Code Block | ||

constexpr int square(int x) { return x*x; }
//NOT
#define SQUARE(r) ((r)*(r))
double square_macro = AREA(4.6); |
Assertions
Occasionally use assert statements to double-check any condition. If the statement inside the assert is false, the program will terminate.

bool value = 8;
assert(value != NULL);
assert(value == 5); //Program will terminate |
