Description : This function assigns the value ‘val’ to all the elements in the range [begin, end), where ‘begin’ is the initial position and ‘end’ is the last position.
Example :
int main () {
std::vector<int> myvector (8); // myvector: 0 0 0 0 0 0 0 0
std::fill (myvector.begin(),myvector.begin()+4,5); // myvector: 5 5 5 5 0 0 0 0
std::fill (myvector.begin()+3,myvector.end()-2,8); // myvector: 5 5 5 8 8 8 0 0
for(int i = 0; i<10; i++)
cout<<myvector[i]<<" ";
std::cout << '\n';
return 0;
