In this program, a vector is declared with few elements and also, a variable s is declared for storing the sum of the elements. On executing the code, the size of the vector is printed using the size() function, and the sum of the elements is printed using a for a loop. Example #...
C++ STL vector::max_size() function: Here, we are going to learn about the max_size() function of vector header in C++ STL with example.
myvector.size(); Output:5 Input :myvector = {} myvector.size(); Output:0 错误和异常 1.它没有异常抛出保证。 2.传递参数时显示错误。 // CPP program to illustrate// Implementation of size() function#include<iostream>#include<vector>usingnamespacestd;intmain(){vector<int> myvector{1,2,3...
我们知道在C/C++中,sizeof() 是一个判断数据类型或者表达式长度的运算符,以字节为单位。 当用sizeof 判断一个vector类型的变量所占的内存大小时,结果会是什么呢? 比如下面这段代码: #include<iostream>#include<vector>usingnamespacestd;intmain(){vector<int>vec;for(inti=0;i<10;i++){vec.emplace_back(...
