Visual Studio C++ 多行注释

Question

In VS C++ code, if i haven't selected anything or full line selected and press comment selection (Ctrl+K + Ctrl+C) then it will comment the whole line with //

int x = 5;

After Pressing Ctrl+K + Ctrl+C without anything selected or full line selected.

// int x = 5;

Now if I select some part of the line and press comments button again only selected text will be commented (bold means selected)

int x = 5 ;

After Pressing Ctrl+K + Ctrl+C with x = 5 selected.

int /*x = 5*/;

Incase of multiple lines

int x = 5;

int y = 2;

int z = x * 5;

And after comments shortcut

int/* x = 5;
int y = 2;
int z =*/ x * 5;

What I want

//int x = 5;
//int y = 2;
//int z = x * y;

Now this is what I don't like. Usually I select multiple lines and press comments button. This will comment only the selected characters , but I want all selected lines tobe commented. Is there anyway to do that any extension or from visual studio settings I can change that?

Answer 1

You have to select the whole line (ie from the very first character of the line) in order to use c++ comments for multiple lines too.

Update: if there are comments among the selected lines, Ctrl+K,Ctrl+C will generate C++ style comments even if the selection does not start from the beginning of the lines.

Answer 2

Triple click on the first line and while keeping the mouse button pressed drag to the bottom (end) line. after that you have easy select the whole lines and pressing the Ctrl+K, Ctrl+C will comment all those lines with "//" in front.

Answer 3

If you select a block of code and use the key sequence Ctrl+K+C, you'll comment out the section of code. Ctrl+K+U will uncomment the code.

Answer 4

Single Line Comment Shortcut

To achieve more than one single line comment, select the lines and use ctrl + / .

According to ques asked, just use the above shortcut, instead of what you are using to achieve what you want.

Multiline Comment Shortcut

Additionally, instead of such a long shortcut(mentioned in ques). To do multiline comments, select the text and use ctrl+shift+a .

Same shortcuts are used to uncomment.
