MCQ
Interview Question
C++ Vector at()It gives a reference to an element. SyntaxConsider a vector v and k is the position. Syntax would be: Parameterk: k defines the position of element which is to be returned by at() function. Return valueIt returns the element of specified position. The following illustration shows how at() function worksIf i=0 : 
If i=3 : 
ExampleLet's see a simple example. Output: 1234 In this example, at() function access the elements of vector .
