Vector Library end() Function in C++ Programming Language

Vector Library end() Function in C++
Return iterator to end. Returns an iterator referring to the past-the-end element in the vector container. The past-the-end element is the theoretical element that would follow the last element in the vector. It does not point to any element, and thus shall not be dereferenced. Because the ranges used by functions of the standard library do not include the element pointed by their closing iterator, this function is often used in combination with vector::begin to specify a range including all the elements in the container. If the container is empty, this function returns the same as vector::begin.
Syntax for Vector end() Function in C++
#include <vector> iterator end() noexcept; const_iterator end() const noexcept;
This function does not accept any parameter. Function returns an iterator to the element past the end of the sequence. If the vector object is const-qualified, the function returns a const_iterator. Otherwise, it returns an iterator. Member types iterator and const_iterator are random access iterator types (pointing to an element and to a const element, respectively). To use vector, include <vector> header. It does not point to the last element, thus to get the last element we can use vector::end()-1.
Iterator validity
No changes
Data races
The container is accessed (neither the const nor the non-const versions modify the container). No contained elements are accessed by the call, but the iterator returned can be used to access or modify elements. Concurrently accessing or modifying different elements is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions. The copy construction or assignment of the returned iterator is also guaranteed to never throw.

Following C++ program first ask to the user to enter the value of n and then ask to enter the n Number to add them. This program add all n numbers entered. To add n numbers in C++

To find the frequency of character in string in C++, enter the string and enter the character to Find the Frequency of that character (or to "count the occurrence of character") in string

Ask to enter two time periods and these two periods are stored in structure variables t1 t2 respectively. The computeTimeDifference() Function calculates the Difference Between

In C++ program, we have the variable i inside "Switch Braces", which means whatever the value of variable i is, the 'corresponding' case block gets executed. We have passed integer

To make a simple calculator in the C++, which performs basic four mathematical operations (addition, subtraction, multiplicatin, division) depending on the "user's choice", switch case

Capacity is the capacity of the "binary heap". Duplicates are allowed. "Throw Overflow" if container is full. Find the smallest item in the "priority queue". Return the smallest item, or

In this C++ example, we have "two functions" one gets the values from user, assign them to structure members and returns the structure and the other function takes that structure as

Swap numbers means exchange the values of two variables with each other. Variable num1 contains 20 and num2 contains 40 after swap there values num1 contains 40 num2 contains
