### C + + vector (vector) use of methods to explain (sequential access vector in a variety of ways) _c language

Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it: Copy Code code as follows: #include Vector initialization: There are five ways to do this, examples are as follows: (1)
