C++ STL 2D Vector: Here, we are going to learn about the vector of vector or 2D vector in C++ STL, its declaration with user defined size.
//C++ STL program to create an empty vector//and initialize by pushing values#include<iostream>#include<vector>usingnamespacestd;intmain(){//vector declarationvector<int>v1;//pushing the elementsv1.push_back(10);v1.push_back(20);v1.push_back(30);v1.push_back(40);v1.push_back(50)...
下例使用 for 循环把 vector 中的每个元素值都重置为 0: // reset the elements in the vector to zero for (vector<int>::size_type ix = 0; ix != ivec.size(); ++ix) ivec[ix] = 0; 在上例中,即使 ivec 为空,for 循环也会正确执行。ivec 为空则调用 size 返回 0,并且 for 中的测试...

The simplest creation method is declaration without size specification, that is, without memory allocation for the data. Here, we just write the data type and the variable name: matrix matrix_a; // double type matrix matrix<double> matrix_a1; // another way to declare a double matrix, suit...
