{<br />
	vector<char> v{‘C’,’+’,’#’};<br />
	v.erase(v.begin()+1);<br />
	for(int i=0;i<v.size();i++)<br />
	cout<<v[i];<br />
	return 0;<br />

using namespace std;<br />
int main()<br />
{<br />
vector<string>  fruit{“mango”,”apple”,”strawbery”,”kiwi”,”banana”};<br />
cout<<“fruit names are :”;<br />
for(int i=0;i<fruit.size();i++)<br />
cout<<fruit[i]<<” “;<br />
cout<<‘\n’;<br />
fruit.erase(fruit.begin()+1,fruit.begin()+3);<br />
cout<<“After removing apple and strawbery fruits,”<<‘\n’;<br />
