Vector : The Standard Template Library (STL) includes the collection of data types and algorithms which can be used by the programmer in their programs. A special data type called vector is offered by STL which is useful for standard arrays. A vector stores the elements or values in sequence order and the values are stored in continuous memory locations. The subscript operator “[]” in the vector helps to read the content of each element. Initialization of vector: In C++, the vector is initialized with the respective value as like the array but it does not use the “=” operator before the list and uses the keyword “vector”. The initialization list values are enclosed with the braces. Consider the following statement: //Declaring a vector with four values vector <int> values {40, 32, 15, 17}; In the above line, the keyword “vector” represents the vector declaration, “<int>” represents that the vector holds integer type values, “values” represents the name of the vector, and the values inside the braces refers the values of the vector “values”.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.

Program Plan Intro
Vector:
The Standard Template Library (STL) includes the collection of data types and algorithms which can be used by the programmer in their programs.
A special data type called vector is offered by STL which is useful for standard arrays.
A vector stores the elements or values in sequence order and the values are stored in continuous memory locations.
The subscript operator “[]” in the vector helps to read the content of each element.
Initialization of vector:
In C++, the vector is initialized with the respective value as like the array but it does not use the “=” operator before the list and uses the keyword “vector”.
The initialization list values are enclosed with the braces.
Consider the following statement:
//Declaring a vector with four values
vector <int> values {40, 32, 15, 17};
In the above line, the keyword “vector” represents the vector declaration, “<int>” represents that the vector holds integer type values, “values” represents the name of the vector, and the values inside the braces refers the values of the vector “values”.
