# What is the difference??

 P: n/a Hi all, What is the difference in both types of intializations?. Class Abc { int x,y,z; public: Abc() { x=0, y=0, z=0; } }; Class Abc { int x,y,z; public: Abc():x(0),y(0),z(0) { } }; Is there any difference in these 2 kinds of intializations?. Which one could be better to use?. Thanking you. Dec 26 '06 #1

Which one could be better to use?. The first one is not initialization, it's assignment. The answer to your question is in the FAQ: http://www.parashift.com/c++-faq-lit....html#faq-10.6 HTH, - J.

Class Abc { int x,y,z; public: Abc() { x=0, y=0, z=0; } Thats a syntax error: Abc() { x=0; y=0; z=0; } }; Class Abc { int x,y,z; public: Abc():x(0),y(0),z(0) { } }; Is there any difference in these 2 kinds of intializations?. Which one could be better to use?. The first would allocate and then assign, the second allocates + initializes simultaneously. Dec 26 '06 #3

It actually achieves the same effect as: Abc() { x=0; y=0; z=0; } Look up 'comma operator'. -Mike Dec 27 '06 #6
