How to Initialize a Vector When Declaring the Vector in C++ */ #include <iostream> #include <vector> int main() { //initialization at the time of declaration std::vector<std::string> vec{ "aticleworld", "amlendra","pooja"}; for (std::string x : vec) { std::cout << x << "...
This constructor allows us to create a new vector and initialize it with the elements from an existing range, such as another vector. The syntax for using the range constructor to initialize a vector of structs is as follows: std::vector<StructType> newVector(existingVector.begin(), existing...

We declare a static integer variable count and initialize it with the value 0. Next, we use the post-increment operator (++) to increase the value of count by 1 and then print its value using the std::cout statement. In the main() function, we call the incrementAndPrint() function th...
