how to use own objects as elements of STL vector

[saurabh1]

hi,,
actually i want to know how to use own objects as elements in STL vector.
we can easily use int, float , char etc. as the elements of vector, but how to use own created objects as the element of vector.....

Hi,
The mode of usage remains the same for created objects.
Check this

class A
{
int x;
};
vector <A> AVect;
 

Thanks

actually this code is not working..
when i create the obejct and then use the push_back() function, it gives some exception .
can you provide me the full code as how to use the push_back() function in this case to add object to vector.

Hi,
Check this code...

#include<iostream>
#include<vector>
#include<string>
 
using namespace std;
 
class Test
{
private:
    string m_name;
    int m_age;
public:
    Test(string _name,int _age)
    {
        m_name.assign(_name);
        m_age=_age;
    }
    void Print()
    {
        cout<<m_name<<" age is "<<m_age<<endl;
    }
};
 
Test CreateTest(char* _name,int _age)
{
    string memStr(_name);
    Test retTest(_name,_age);
    return retTest;
}
 
int main()
{
    vector<Test> TVector;
    Test t1 = CreateTest("A",10);
    TVector.push_back(t1);
    t1 = CreateTest("B",20);
    TVector.push_back(t1);
    t1 = CreateTest("C",30);
    TVector.push_back(t1);
 
    vector<Test>::iterator TVIter;
    for(TVIter=TVector.begin();TVIter!=TVector.end();TVIter++)
    {
        (*TVIter).Print();
    }
 
 
}
