You can also use C++ Foreach statement to get the length of size of a vector. In the following program, we shall define a vector and initialize with elements. Then take a len variable with zero initial value that acts as a counter to count the number of elements in the vector.
Web@Happy Vector does not contain the data directly, but contains a pointer to the data elsewhere. To swap two vectors requires only swapping these pointers (plus a few other bits, such as size information). But the operation is in constant time. Swapping an std::array on the other hand, requires swapping every element individually. This is a ...
WebJul 30, 2013 · vector.size() returns the size of a vector. You didn't put any string in the vector before the loop , so the size of the vector is 0. It will never enter the loop.
