C++ doesn't have a power operator, so we define our own macro to compute X2. We've decided to test this macro by printing the squares of the numbers from 1 to 10. But what do we really print?
1 /************************************************
2 * Print out the square of the numbers *
3 * from 1 to 10. *
4 ************************************************/
5 #include <iostream>
6
7 /*********************************** ************
8 * macro to square a number. *
9 ************************************************/
10 #define SQR(x) ((x) * (x))
11
12 int main()
13 {
14 int number; // The number we are squaring
15
16 number = 1;
17
18 while (number <= 10) {
19 std::cout << number << " squared is " <<
20 SQR(++number) << std::endl;
21 }
22
23 return (0);
24 }
