@ -7263,20 +7263,20 @@ The call will most likely be `f(0, 1)` or `f(1, 0)`, but you don't know which. T
**Example**:
for (int m = 1; m<=12; ++m) // don't: magic constant 12
for (int m = 1; m <= 12; ++m) // don't: magic constant 12
cout << month[m] << '\n';
No, we don't all know that there a 12 month, numbered 1..12, in a year. Better:
constexp int last_month = 12; // months are numbered 1..12
constexpr int last_month = 12; // months are numbered 1..12
for (int m = first_month; m<=last_month; ++m) // better
for (int m = first_month; m <= last_month; ++m) // better
cout << month[m] << '\n';
Better still, don't expose constants:
for(auto m : month)
cout << m <<'\n';
cout << m << '\n';
**Enforcement**: Flag literals in code. Give a pass to `0`, `1`, `nullptr`, `\n`, `""`, and others on a positive list.
