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...
for (std::string x : vec) { std::cout << x << " "; } return 0; } Output: aticleworld amlendra pooja In the above example, I am creating a vector of strings and initializing it with the three strings. 2. How to Initialize a Vector From an Array in C++: You can initialize ...
Clearing array elements is a common operation in C++ when you want to reset or initialize the elements to a specific value. In this article, we will explore multiple approaches to accomplish this, allowing you to choose the one that best suits your needs. ...
0 10 20 30 40 In this example, the createVector function creates a std::vector of integers. It initializes the vector with the specified size and fills it with multiples of 10. The vector is returned to the caller, where it can be used just like an array. This method is highly eff...
