In Example 1-1 (Chapter 1), we designed an algorithm to find the perimeter and area of a rectangle. Given the length and width of a rectangle, the C++ program, in Example 2-1, computes and displays the perimeter and area.
The following are identifiers in C++:
First
Conversion
payRate
counter1
Table 2-1 show some illegal identifiers and explain why they are illegal and also gives a correct identifier.
