我有一个类有几个对象作为成员变量.我不希望在声明时调用这些成员的构造函数,所以我试图明确地挂起指向该对象的指针.我不知道我在做什么.O_O

在StackOverflow上,我似乎能够找到对象成员变量的其他示例,但通常会立即调用构造函数,如下所示:

class MyClass {
    public:
        MyClass(int n);
    private:
        AnotherClass another(100); // this constructs AnotherClass right away!
};

但我希望MyClass构造函数调用AnotherClass构造函数.这是我的代码的样子:

BigMommaClass.h

#include "ThingOne.h"
#include "ThingTwo.h"

class BigMommaClass {

        public:
                BigMommaClass(int numba1, int numba2);

        private:
                ThingOne* ThingOne;
                ThingTwo* ThingTwo;
};

BigMommaClass.cpp

#include "BigMommaClass.h"

BigMommaClass::BigMommaClass(int numba1, int numba2) {
        this->ThingOne = ThingOne(100);
        this->ThingTwo = ThingTwo(numba1, numba2);
}

这是我尝试编译时遇到的错误:

g++ -Wall -c -Iclasses -o objects/BigMommaClass.o classes/BigMommaClass.cpp
