可是,这是C++11之后才同意的,之前编译器并不同意你写这种语法。不同意vector容器内放local structure。 更进一步,假设struct里面有好几个字段呢? #include<iostream>#include<string>#include<vector>using namespace std; struct subject { string name;intmarks;intcredits; };intmain() { vector<subject>sub; /...

1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...
string s1 ;// Default initialization; s1 is the empty string.strings2(s1);// s2 is a copy of s1.string s2 = s1 ;// Equivalent to s2(s1), s2 is a copy of s1.strings3("value");// s3 is a copy of the string literal, not including the null.string s3 ="value";// Equivalent...
c++ c++11 templates initialization 有一个名为Matrix的结构,其模板参数N和data_字段: #include <cstddef> #include <vector> template <std::size_t N> struct Matrix { std::vector<std::vector<int>> data_{N, std::vector<int>(N)}; }; 为什么不能用圆括号初始化data_? std::vector<std::...

SL.con.1: Prefer using STL array or vector instead of a C array SL.con.1:标准库array或vector好于C数组 Reason(原因) C arrays are less safe, and have no advantages over array and vector. For a fixed-length array, use std::array, which does not degenerate to a pointer when passed to...
