The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Tracking program memory usage.

Asked by rongz in C++ Programming Language

Tags: memory

Hello,

I want to track the objects created and the byte required for loading each object while a program is running and then dump the results to a file or standard output. I tried using "sizeof()" , but it doesn't work. Can you tell me how to do it? Thanks a lot.

p.s. I want to track memory usage of each object created during the program is running. Not only the total memory usage of the program.

-----------This does not work-----------------

#include <iostream.h>
#include <vector>
using std::vector;

class A1 {
public:
vector<int> x_set; // could be other user define type

public:
A1(){ cout<<"A1 is created\n";} //track it when A1 is instantiated

void setVector(int size, int value){

for(int i=1;i<size;i++)
x_set.push_back(value);
}

int getVectorSize(){
return x_set.size();
}

};

int main(){

cout<<"sizeof(A1) is:"<<sizeof(A1)<<"\n"; //size of class A1?

A1* xp=new A1();

xp->setVector(120,25);

cout<<"sizeof(*xp) is:"<<sizeof(*xp)<<"\n"; //the byte required to load
// the object pointed by xp??

cout<<"set: "<<sizeof(xp->x_set)<<"\n";

cout<<"vector size:"<<xp->getVectorSize()<<"\n";
return 0;
}

/*******Running result

sizeof(A1) is:12
A1 is created
sizeof(*xp) is:12
set: 12
vector size:119
