First, this program imports all the necessary header files such as <iostream> and <vector>. After this, a vector is declared with few elements. On executing the code, the size of the vector is printed using the size() function. Example #2 CPP program that uses size() function in vector...

This post will discuss how to find the index of the first occurrence of a given element in vector in C++. 1. Usingstd::findwithstd::distancefunction The simplest solution is to use thestd::findalgorithm defined in the<algorithm>header. The idea is to get the index usingstd::distanceon ...

Could not found the element 32 in vector Alternatively, we may use thestd::findalgorithm that’s part of the STL library. This function returns the iterator to the first element that satisfies the condition. On the other hand, if no element is found, the algorithm returns the last element...

This post will discuss how to find the min or max value in a vector in C++. 1. Using std::max_element The std::min_element and std::max_element return an iterator to the minimum and the maximum value in the specified range, respectively. The following code example shows invocation for...
