In C++, the vector class provides a function pop_back(). It removes the last element from the calling vector object. Table Of Contents Syntax of vector::pop_back(): Example of vector::pop_back() function Calling vector::pop_back() function on empty vector Remove all elements from vector using vector::pop_back() Summary Syntax of vector::pop_back(): Parameters: None Return value: None It accepts no argument, …
In C++, the vector class provides a member function push_back(). It accepts an element as an argument, and adds that element to the end of the vector. Basically it increases the size of the vector by one. As per vector’s internal implementation, sometimes it might be possible the due to addition of an element at …
In C++, the vector class provides a function clear(). It removes all elements from the calling vector object. It will make the size of vector 0. Table Of Contents Syntax of vector::clear(): Examples of vector::clear() Example 1 Example 2 Summary Syntax of vector::clear(): Parameters: None Return value: None Examples of vector::clear() Let’s see some examples …

Table Of Contents Method 1: using vector::empty() Method 2: using vector::size() Method 3: using vector::begin() & vector::end() Summary Method 1: using vector::empty() In C++. the vector class provides a function empty(). It returns true if the …
In this article, we will discuss different ways to check if two vectors are equal or not. Table Of Contents Method 1: Using == operator Method 2: Using STL algorithm equal() Method 3: Using STL Algorithm mismatch() Method 4: Using custom function Summary Method 1: Using == operator We can directly compare two vectors using …
In this article, we will discuss different ways to check if a vector is sorted or not in C++. Iterate over all the elements of vector by index positions. For each element at ith index, check if it is either smaller or equal to the element at (i+1)th index position. If this condition evaluates to …
In this article, we will discuss different ways to check if all elements in a vector are equal or not. Table Of Contents Method 1: Using STL Algorithm all_of() Method 2: Using for-loop Summary Method 1: Using STL Algorithm all_of() In C++, the STL algorithm provides a function all_of(), to check if a predicate is …
