The <vector> library has many functions that allow you to perform tasks on vectors.A list of popular vector functions can be found in the table below.FunctionDescription assign() Fills a vector with multiple values at() Returns an indexed element from a vector back() Returns the last ...
The template function is an algorithm specialized on the container class vector to execute the member functionleft. vector::swap (right). These are instances of the partial ordering of function templates by the compiler. When template functions are overloaded in such a way that the match of the...

int first = vec.front(); // first will be 1 int last = vec.back(); // last will be 5Code language: C++ (cpp) Performance Considerations: Both front() and back() are O(1) operations. They do not have boundary checks. If the vector is empty and these functions are used, the ...
Unlike other functions, no parameters are passed in this. Return value: Count of items in the container. Exceptions and Errors Do not guarantee exception throw. When parameters are passed, errors are thrown. How to find the size of vector in C++?
