C++ vector address
WebFor a C++ program, the memory of a computer is like a succession of memory cells, each one byte in size, and each with a unique address. These single-byte memory cells are ordered in a way that allows data … WebReturns a reference to the element at position n in the vector. The function automatically checks whether n is within the bounds of valid elements in the vector, throwing an out_of_range exception if it is not (i.e., if n is greater than, or equal to, its size).This is in contrast with member operator[], that does not check against bounds. Parameters n ...
