Jurcau 3,010 11 21 There are different ways to initialize a vector in C++. Method 1: Here, we are initializing the vector by providing values directly to the vector. Now, both vector1 and vector2 are initialized with values 1, 2, 3, 4, 5. Method 2: Here, 5 is the size of the vector and 12is the value. This code creates an int vector with … See more Once we include the header file, here's how we can declare a vector in C++: The type parameter specifies the type of the vector. It can be any … See more To add a single element into a vector, we use the push_back()function. It inserts an element into the end of the vector. For example, Output Here, we have initialized an int vector num with … See more The vectorclass provides various methods to perform different operations on vectors.
