C ++向量pushback（）和popback（）函数

Question

I have a vector and would like to write my own functions for school purposes and im stuck.

void push_back(int value)
void pop_value();

i would like to implement functions in main like this

iv2.push_back(100)
iv2.push_back(101) // will cause exception to be thrown.

can someone please show me how to write these functions out so i can understand what they are doing. Let me know if you need more of my class.

class int_vector {


public:
        //deafault constructor
        int_vector() : capacity_(minCapacity_), size_(0), data_(new int[capacity_]) {
            cout << "default constructor of: " << this << "\n";
        }

...


private:


void push_back(int value) {}?
void pop_value(){}

....

You can look at how a vector is implemented at https://github.com/lnishan/vector/blob/master/vector.hpp

I hope it helps.
