Exemple #1

Fichier : smartPointer.c Projet : cydrain/Coding_Practice

int main(void) {  
    int *pi = new int(42);

    HasPtr *hpb = new HasPtr(*hpa);     // 拷贝构造函数
    HasPtr *hpc = new HasPtr(*hpb);     // 拷贝构造函数
    HasPtr hpd = *hpa;     // 拷贝构造函数

    int *pj = new int(314);
    hpc = new HasPtr(pj, 200);

    cout << hpa->get_ptr_val() << " " << hpb->get_ptr_val() << endl;
