erase() in c++ code example
Example 1: removing a character from a string in c++
#include<iostream>
#include<algorithm>
using namespace std;
main() {
string my_str = "ABAABACCABA";
cout << "Initial string: " << my_str << endl;
my_str.erase(remove(my_str.begin(), my_str.end(), 'A'), my_str.end());
cout << "Final string: " << my_str;
}
Example 2: erasing a character from a string in c++
#include <iostream>
#include <string>
int main ()
{
std::string str ("This is an example sentence.");
std::cout << str << '\n';
str.erase (10,8);
std::cout << str << '\n';
str.erase (str.begin()+9);
std::cout << str << '\n';
str.erase (str.begin()+5, str.end()-9);
std::cout << str << '\n';
return 0;
}
Example 3: delete from front in vector c++
vector_name.erase(vector_name.begin());
vector_name.erase(vector_name.begin()+(x-1));
vector_name.pop_back();
Example 4: erase an element from vector c++
#include<bits/stdc++.h>
using namespace std;
int main(){
vector<int> v;
v.push_back(20);
v.push_back(10);
v.push_back(30);
v.push_back(20);
v.push_back(40);
v.push_back(20);
v.push_back(10);
vector<int>::iterator new_end;
new_end = remove(v.begin(), v.end(), 20);
for(int i=0;i<v.size(); i++){
cout << v[i] << " ";
}
return 0;
}

Example 5: c++ erase remove
std::vector<int> v = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
v.erase(std::remove(v.begin(), v.end(), 5), v.end());
