- | #define is used for creating names that will overwrite the current event. | ||
- | |||
- | For example: | ||
- | |||
- | <code cpp> | ||
- | |||
- | // we are going to make a program that will use a #define for replacing a number | ||
- | |||
- | #include <iostream> | ||
- | #include <cmath> | ||
- | |||
- | #define INT_FIVE int i = 5; | ||
- | #define DOUBLE_FIVE double d = 5; | ||
- | |||
- | int main() { | ||
- | |||
- | cout << "The normal square root of 5 is: " << sqrt(DOUBLE_FIVE) << endl; | ||
- | cout << "The int square root of 5 is: " << (int)sqrt(INT_FIVE) << endl; | ||
- | return 0; | ||
- | } | ||
