C++ Vector erase
It deletes the specified elements pointed by the iterator
Erases third element using erase function
Syntax
Consider a vector v. Syntax would be:
Example
v.erase(pos);
v.erase(start_iterator,end_iterator);
Parameter
pos : It defines the position of the element which is to be removed from the vector.
(startiterator,enditerator) : It defines the range of the elements to be removed from the vector.
Return value
It does not return any value.
Example 1
Let's see a simple example.
Example
#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<char> v{'C','+','#'};
v.erase(v.begin()+1);
for(int i=0;i<v.size();i++)
cout<<v[i];
return 0;
}
Output:
Example 2
Let's see a simple example
Example
#include<iostream>
#include<vector>
using namespace std;
int main()
{
vector<string> fruit{"mango","apple","strawbery","kiwi","banana"};
cout<<"fruit names are :";
for(int i=0;i<fruit.size();i++)
cout<<fruit[i]<<" ";
cout<<'\n';
fruit.erase(fruit.begin()+1,fruit.begin()+3);
cout<<"After removing apple and strawbery fruits,"<<'\n';
for(int i=0;i<fruit.size();i++)
cout<<fruit[i]<<" ";
return 0;
}
Output:
Output
fruit names are :mango, apple,strawberry, kiwi, banana
After removing apple and strawbery fruits,
Mango, kiwi, banana
