How can I use “#include ”?
I am currently working on a competitive task related to programming in which I need to solve an issue that includes various database structures such as vector sets, and algorithms like sortings. How can I use the “#include
In the context of competitive programming development, the feature of “#include ” is mainly a shortcut for including the entire standardized library in the C++ programming language. It is very useful and beneficial as it saves time by using the technique of commonly used headers such as , , , etc., all at once.
Here is the example given of how you use this feature in Java programming language:-
#include
Using namespace std;
Int main() {
Vector numbers = {4, 2, 7, 1, 5};
// Sorting the vector using sort() from
Sort(numbers.begin(), numbers.end());
// Iterating through the sorted vector
For (int num : numbers) {
Cout << num>In the above example, the feature of “#include ” acts as a saving guard from headers like , , , , etc.
