Removes an element or a range of elements in a vector from specified positions.
iterator erase(
const_iterator_Where
);
iterator erase(
const_iterator _First,
const_iterator_Last
);
Parameters
Parameter |
Description |
_Where |
Position of the element to be removed from the vector. |
_First |
Position of the first element removed from the vector. |
_Last |
Position just beyond the last element removed from the vector. |
Return Value
An iterator that designates the first element remaining beyond any elements removed, or a pointer to the end of the vector if no such element exists.
Example
// vector_erase.cpp
// compile with: /EHsc
#include <vector>
#include <iostream>
int main( )
{
using namespace std;
vector <int> v1;
vector <int>::iterator Iter;
v1.push_back( 10 );
v1.push_back( 20 );
v1.push_back( 30 );
v1.push_back( 40 );
v1.push_back( 50 );
cout << "v1 =" ;
for ( Iter = v1.begin( ) ; Iter != v1.end( ) ; Iter++ )
cout << " " << *Iter;
cout << endl;
v1.erase( v1.begin( ) );
cout << "v1 =";
for ( Iter = v1.begin( ) ; Iter != v1.end( ) ; Iter++ )
cout << " " << *Iter;
cout << endl;
v1.erase( v1.begin( ) + 1, v1.begin( ) + 3 );
cout << "v1 =";
for ( Iter = v1.begin( ) ; Iter != v1.end( ) ; Iter++ )
cout << " " << *Iter;
cout << endl;
}
v1 = 10 20 30 40 50 v1 = 20 30 40 50 v1 = 20 50
