From this, we can see that there are 5 elements in the vector. So, when we call the size() function, the result will display the size of the vector as 5. It can be used while performing addition operations in the vector. Instead of mentioning the size, the size() function can be ...
C++ STL的 size 表示元素数量是正确的，因为 size 针对的确实就是元素。vector的底层并不保证是字节。...
