# What is the easiest way to initialize a std::vector with hardcoded elements in C++?

C++Server Side ProgrammingProgramming

In modern C++ [11,14,…] a vector is initialized in the following way

std::vector<int> vec = {1,2,3};

## Algorithm

Begin
Initialize the vector v.
Using accumulate, sum up all the elements of the vector v is done.
Print the result.
End.

Here is a simple example of sum up the elements of a vector:

## Example

Live Demo

#include<iostream>
#include<vector>
#include<numeric>
using namespace std;
int main() {
vector<int> v = {2,7,6,10};
cout<<"Sum of all the elements are:"<<endl;
cout<<accumulate(v.begin(),v.end(),0);
}

## Output

Sum of all the elements are:
