c++ remove class from vector code example
Example 1: c++ remove class from vector
#include <algorithm>
#include <vector>
#include <iostream>
class MyClass
{
public:
std::string Name;
};
std::vector<MyClass> MyClass_Vector;
int main()
{
MyClass myclass_1;
MyClass myclass_2;
MyClass myclass_3;
MyClass myclass_4;
MyClass myclass_5;
myclass_1.Name = "Name_1";
myclass_2.Name = "Name_2";
myclass_3.Name = "Name_3";
myclass_4.Name = "Name_4";
myclass_5.Name = "Name_5";
MyClass_Vector.push_back(myclass_1);
MyClass_Vector.push_back(myclass_2);
MyClass_Vector.push_back(myclass_3);
MyClass_Vector.push_back(myclass_4);
MyClass_Vector.push_back(myclass_5);
std::cout << "Before " << MyClass_Vector.size() << "\n";
for(int i = 0; i < MyClass_Vector.size(); i++) std::cout << MyClass_Vector[i].Name << "\n";
std::string Name_Of_Class_To_Delete = "Name_2";
MyClass_Vector.erase(std::remove_if(MyClass_Vector.begin(), MyClass_Vector.end(), [&Name_Of_Class_To_Delete](const MyClass& myclass)->bool
{
return myclass.Name == Name_Of_Class_To_Delete;
}), MyClass_Vector.end());
std::cout << "\nAfter " << MyClass_Vector.size() << "\n";
for(int i = 0; i < MyClass_Vector.size(); i++) std::cout << MyClass_Vector[i].Name << "\n";
return 0;
}
Example 2: vector remove class
carVec.erase(std::remove_if(carVec.begin(), carVec.end(), [&id_to_delete](const Car& ele)->bool
{
return ele.getnewId() == id_to_delete;
}), carVec.end());
