Manage code?

You can achieve so much with them

Except for code completion, navigation, warnings even without compilation.

For Vim: YouCompleteMe and then some for warnings and errors https://images.elixi.re/i/rruyyyof.png

And then this can turn Vim into an even more complete IDE: https://vim.fandom.com/wiki/Use_Vim_like_an_IDE

old? 13 December 2019

Oh, is that the first release?

Initial release was 2 November 1991.

kinda like saying visual studio is old because it was there in the 2000s

Not vs code tho :-)

but vs is not old

VS or VS Code?

I honestly cannot understand using an IDE for a language that doesn't have lots of unrememberable imports, such as Java.

Because #include are so much easier to remember 😂

After writing Java for many years, I still couldn't make a hello world program without autoimport.

Why is this a problem if any decent IDE can autimport?

It's not really a problem, since I don't write Java anymore and when I did, I used an IDE.

for(i=0;i<n;i++) { for(j=m-1;j>=0;j--) { printf("%d ",matrix[j][i]); } printf("\n"); }

for(i=0;i<n;i++) { for(j=m-1;j>=0;j--) { printf("%d ",matrix[j][i]); } printf("\n"); }

Hey boys, I'm trying to compare a Student object to an array of Students of the class Exam So I need to overload the == operator and put it in the Student class My problem is, I've seen many methods like className returnType operatorSomething(etc) But also Friend returnType operator etc So I don't get when to use class name and when friend

For operators it's usually preferable to use non member friend functions. You can read more here https://stackoverflow.com/questions/4622330/operator-overloading-member-function-vs-non-member-function

but there is also a way to have a directory mapped in memory ?

I have a map<string, vector<string>> and suppose I've calculated map["hi"] = some_vector_of_strings then if I want to assign map["hello"] = map["hi"] and after this statement, I don't need map["hi"] forever. Is there a faster way to assign map["hello"] with the vector that map["hi"] has?

You wouldnt be able to modify files in that directory

why? maybe I will lost these changes

Thats why

Do you care about the contents of map you're copying from/to? Do keys between maps has any correlation? What about previous values? Should they be overwritten or new vector should be appended ?

The keys don't have any relation. It is just that both the keys have same value. Now, copying a new vector is expensive so I want the value(here vector) to be transferred.

If keys have the same values there is no need to copy anything. If you want to append and you do this operation a lot - consider using std::list and splice http://www.cplusplus.com/reference/list/list/splice/
