答案是:20(G++编译器下) 了解string,int的朋友很熟悉,string和int在G++下都是4字节,这样看来 grades的大小应为12字节。 给grades中放入三个整型值,100,110,120,sizeof(grades),竟然还是12! 由此说来,sizeof(vector<type>)的大小,跟容器里面存放多少数据无关,它是在编译期确定的一个值,仅跟具体的编译器有...
由此可以看出:sizeof(vec)只取决于vector里面存放的数据类型,与元素个数无关。该值应该是与编译器相关的。 1 #include <iostream> 2 #include <vector> 3 using namespace std; 4 int main() 5 { 6 cout<<"sizeof(vector<char>) = "<<sizeof(vector<char>)<<endl; 7 cout<<"sizeof(vector<int>...
发现sizeof(vec) 为24,并不等于 10 * sizeof(int) = 40。这是为什么呢? 这是因为 vector 是C++标准库中的容器类,其可以理解为一个动态数组,其内部实现有三个指针: pointer _M_start; pointer _M_finish; pointer _M_end_of_storage; 分别代表其使用内存的开始、结束,以及分配的内存结尾,其中 _M_finis...
关于C++中vector< vector >的含义.vector< vector > vvec;的意思是:定义了一个vector,这个vector的element也是一个vector,那么我要问的是,对于内层的vector,编译系统知道每个element的size为sizeof(int),而对于外层

The dynamic array can be created by using a vector in C++. One or more elements can be inserted into or removed from the vector at the run time that increases or decreases the size of the vector. The size or length of the vector can be counted using any loop or the built-in ...
Designing a vaccine against Plasmodium vivax has focused on selecting antigens involved in invasion mechanisms that must have domains with low polymorphism for avoiding allele-specific immune responses. The rhoptry neck protein 4 (RON4) forms part of the
