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.
No, an array must be contructed with a size, like x_coloredcode string[][] arrays = new string[0][0]; Or give it default values. Wednesday, January 24, 2007 11:24 PM In this style of 2D array (this is a "jagged" array), you must provide the first size (even if it's just...
