myvector.push_back(0); Output:5,4,3,2,1,0 错误和异常 1. 强异常保证——如果抛出异常,容器没有变化。 2. 如果向量不支持作为参数传递的值,则会显示未定义的行为。 C++ // CPP program to illustrate // push_back() function #include<iostream> ...
复习动态数组时,出现了找不到标识符的问题,原因是cpp编译时是“顺序编译”的,主函数调用vector_2()函数的时,vector_2()在它所调用的函数printfV()的定义之前,因此找不到标识符。 将两函数调换顺序即可编译通过 (标识符:标识符是用来标识变量、函数、类、模块,或任何其他用户自定义项目的名称,用它来命名程序正...
The sample declares an empty vector of integers. It adds three integers to the vector, and then deletes one. Finally, it generates the remaining elements in the vector. Example // Pushpop.cpp // compile with: /EHsc // Illustrates how to use the push and pop member // functions of the...
