Memory usage of a C++ program with CLASS and without CLASS

[nsw1216]

Hi all,

I developing a C++ Program to deal with huge data computation. I am using Pointers to hold the data during computation. Current program i developed without using CLASS.

I would like to ask that will the memory usage will be reduced and computational time will be shortened if I modified my program implementing the CLASS into it ?

Hope can get some suggestions to improve my program.

Thanks.

You will use more memory and generally get a slightly worse performance when you use classes.
Of course it highly depends on your specific implementation and difference might be from practically zero to quite a lot.
Unless you do some bad programming (use a lot of small classes, use often copying constructors etc.) performance should be basically equal and it's important to optimize the algorithm and specific code sequences which take most time.

Thanks for the explanations, MirekCz.

So, is there any suggestions that I can reduce the usage of memory during the computation process ?

I´m not totally sure, but I presume that using the inline statement could improve code size, and consequently could reduce dynamic memory usage.

Hi, Andre_teprom.

Thanks for your suggestion. But may I know any info I can refer regarding to the inline statement ?
