In C++, the vector has an empty() function that helps check whether the vector container has elements. Vectors are almost similar to dynamic arrays, which have the facility to resize itself automatically when an item is deleted or inserted, with its storage able to handle automatically by the ...
Usually when I write my own code, I try to make my functions vectorized, so that you can call them with both a single element or with a vector. But in this case, I wasn’t allowed to modify the code to make the function vectorized. So how do we easily vectorizepatient_name()without...
Note that, to print the character % to the console using the printf function, we should use %%. #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}; vector<int> ...
I have already written an article that explains how is the function pointer work in C programming. If you are the then it is my advice that before reading this article you should read my articleHow to use a function pointer in C?
Usestd::mapto Store Multiple Callback Functions With Corresponding Keys in C++ A common way of using callback functions is to store them in the data structure likevectorormap, from which we can easily access each one of them and call the specific function during program run-time. In this ...
Example 1: Basic Application of which FunctionExample 1 illustrates how to use the which() function in the R programming language. First, we have to create some example data:x <- c(1, 5, 4, 8, 4) # Create example vector x # Print example vector # 1 5 4 8 4...
How to determine if a vector is in a range of a transformation? Is the vector function F(x,y,z) = (yz, xz, xy) conservative? Starting with the vector a=(-4, -2): (a) Transform a to b=(4,-2). (b) Transform a to c = (4, 2). ...
I have 1*1050 duble vector (a) in my workspace. I want use this array in a ".c" file. How can this conversion? For example my matlab array is: a = [1 2 3 4 5]; I want convert this vector into: uint16_t a[5] = {1,2,3,4,5} usable in...
Definition of C++ Find Element in Vector C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing th...
Finding sum of vector elements Tofind the sum of the elements, we can useaccumulate() functionwhich is defined in<numeric>header in C++ standard template library. It accepts the range of the iterators in which we have to find the sum of the elements; it also accepts a third parameter whic...
