append():可以使用append()来追加C字符串类型。 push_back():不可以使用push_back()来追加C字符串类型。 // CPP code for comparison on the basis of // Appending C-string #include <iostream> #include <string> using namespace std; // Function to demonstrate comparison among // +=,...
// Function to demonstrate push_back() void push_backDemo(string str1, string str2) { // Appends character by character str2 // at the end of str1 for(int i = 0; str2[i] != ''; i++) { str1.push_back(str2[i]); } cout << "After push_back : "; cout << str1; }...
没有名字的对象，比如字面值（5，true）或者是表达式的结果（1 + 2、someFunction()）。
The syntax flow is in a way as represented : Name_Of_Vector:As its name suggests the Name_Of_Vector is given as a C++ initial. Push_back:This represents push_back as a function. argument:It represents a parameter that is passed to the function at the end of vector. ...
The element is constructed in-place by callingallocator_traits::constructwithargsforwarded. A similar member function exists,push_back, which eithercopies or movesan existing object into the container. 简而言之,push_back会构造一个临时对象,这个临时对象会被拷贝或者移入到容器中,然而emplace_back会直接根...

In older tbb there is push_back function, when we insert in vector using push_back function it can return iterrator or index of element while inserting it. Old Tbb push_back function : #if TBB_DEPRECATED size_type push_back( const_reference item ) #else /** Returns iterator...
