Using to find() function just to check whether the element is present or not. Code: #include<iostream>#include<vector>#include<algorithm>usingnamespacestd;intmain(){// Initializing the vector elementsvector<int>vec={100,200,300,400,500,600,700};//Inputting the element to be searched in ...
Another method of summing up the elements of a C++ vector is to use aforloop. When using aforloop, the programmer defines a variable to hold the sum and starts iterating through thevector. The sum variable is increased with the current element’s value at each iteration. When the loop f...
vector<int> vector1{ 1, 2, 3, 4, 5, 6, 7,8 }; vector<int>::iterator it1; cout<<"ORIGINAL INTEGER VECTOR ELEMENTS ARE: "; for (auto it = vector1.begin(); it != vector1.end(); ++it) cout << ' ' << *it; //Giving the address of the element to be removed it1 = ...
Use theerase()Method to Remove Element From Vector in C++ Theerase()method is a member function of thestd::vectorclass and is capable of a single element of the vector or the range specified as[first, last]. The function returns an iterator following the last removed element. If a single...

The numbers.begin() is the first iterator's setting, which points to the start of the vector, and numbers.end() is set as the final iterator (pointing to the vector's final element). Each element in the range is first compared to the value 30 by the function before iterating over th...
vector<int> y; And I want to sort if in terms of the int values of each vector element, then I can sort by using the stl::sort function, with the comparison function defined as: Code: static bool SortFunction(int val1, int val2) { ...
The code proceeds to add the copied elements into v2 and displays them.Output:As seen in the output above, the push_back() function successfully copies the contents of the v1 vector into the v2 vector. The code also changes the first element of the v1 vector, which, in this case, ...
In this case, it's always "1". But when I try to put "iVec[1]" or something to see the element other than the first, it has error messages such as "overloaded operator not found".How can I view the second element in the vector? What should I type as the variable name in the...
In this C++ tutorial, you shall learn how to join elements of a vector into a string, by a delimiter, with example programs.
