In this blog post, you will learn how to initialize a vector in C++ with the help of C++ programs. I have already written an article on vectors if you want you can check it; “C++ vectors“. Now comes the topic of how we can initialize the C++ vector. I will go through the ...
The following code sample shows the std::modulus function object utilized on vectors of integers. #include <ctime> #include <iostream> #include <vector> using std::cin; using std::cout; using std::endl; using std::vector; int main() { vector<int> ivec1{24, 24, -24, -24, 24}; ...
Background: I have a beginner knowledge and experience with vectors, so I know how to use it. Question: Imagine you are given this unsorted set of vectors: vector <int> unsorted = {12, 36, 7, 50, 3, 80, 2}; Explain how I can make this sorted like this output : 2...
Then push it back to the 2D vector as element. The element of 2D vector (vector of vector in our discussion) is a 1D vector. We can create the vector of vectors in that way. The above code has liberty of adding as much column and row as per user need. It’s totally customized, ...
As we can see in the main function, two vectors are declared: f_vec, a vector of floats, and i_vec, an empty vector of integers.Then, reserve is called on i_vec to preallocate memory for i_vec based on the size of f_vec. This improves efficiency by reducing the number of realloc...

- allocating many vectors in a loop when one or several could be reused instead; - incurring unneeded copies of elements; - forgetting to reserve memory space for elements ahead-of-time; - forgetting to mark the element type's move constructor noexcept; - not making use of allocators. Don...

Thus, we go for make files and we use to make a tool to build the project and generate the executable. We have already seen various parts of a make file. Note that the file should be named “MAKEFILE” or ‘makefile’ and should be placed in the source folder. ...
