在进行push_back操作时,如果出现2D向量的分割错误,可能是由于以下几个原因导致的: 数据类型错误:在进行push_back操作时,需要确保将正确的数据类型添加到2D向量中。如果添加的数据类型与2D向量的定义不匹配,就会导致分割错误。例如,如果2D向量定义为vector<vector<int>>,但尝试将其他类型的数据添加到其中,就会导致分割...

C++ STL vector::push_back() function: Here, we are going to learn about the push_back() function of vector header in C++ STL with example. Submitted by IncludeHelp, on May 15, 2019 C++ vector::push_back() functionvector::push_back() is a library function of "vector" header, it ...
C++ 11向量push_back模糊不清 C++ 11中的向量(vector)是一种动态数组,它可以在运行时根据需要自动调整大小。push_back是向向量末尾添加元素的方法。 具体来说,C++ 11中的向量是一个模板类,可以存储任意类型的元素。它通过动态分配内存来管理元素,并提供了一系列方法来操作和访问这些元素。
has been reduced to allocate data types at the time of compilation itself at the time of inserting element from back of vector. Push_back supporting vectors can be used with different data types including int, string, float, and 2D vector. Using push_back function is an extremely inexpensive...
