First, this program imports all the necessary header files such as <iostream> and <vector>. After this, a vector is declared with few elements. On executing the code, the size of the vector is printed using the size() function. Example #2 CPP program that uses size() function in vector...
Use the transform() Function to Convert a Vector to an Array Use the for Loop to Convert a Vector to an Array Conclusion C++ programmers often encounter scenarios where the transition from a std::vector to a traditional array is necessary. This can be prompted by the need to interface...
