I am not sure about your issue, but should it be &(subj->height)? You said you want to pass address of a field

Sorry, can anyone explain how to sort singly linked list?... I mean using only pointers, no just changing data

the same, but instead of changing values you should change nodes. you could google how to change nodes

I found some codes, but there's no explanation

In this case NULL to key/value is assigned as value/&key !! You may godbolt🙃 std::unordered_map<std::string, int> umap; umap["value"]; Corrected!

Aj correcting my mistake!! Value stored to “key” is NULL, not 0 or &ref

Many of questions we use like this Unordered_map<int , int> map; For( int i=0 ;i<10;i++) map[i]++; It means the value initialze to the key is 0 and then we increment it . Correct me if I am wrong

Here! Check out and run! #include <iostream> #include <unordered_map> int main(void) { std::unordered_map<char *, int> xmap; xmap["aaa"]=45; xmap["bbb"]; std::cout << xmap.at("aaa") << std::endl; std::cout << xmap.at("bbb") << std::endl; std::printf("=%s\n", xmap.at("bbb")); auto x = xmap.at("bbb"); std::printf("\n=%s", x); return 0; }

They gave good list of examples how to use it! Check out! https://docs.microsoft.com/en-us/cpp/standard-library/unordered-map-class?view=msvc-160

can you show @ the struct?

Thanks a lot for example and this doc

yes thats why i asked for the struct, height is not a pointer is a value

in the function you have to call by address

Hello

Do you know c++?

Yes

Sorry, can anyone explain how to sort singly linked list?... I mean using only pointers, no just changing data

I still can't find anything... Did anybody do it before?...

int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = &(r->data).at(i); rootAscii = rootAscii + int(x); //cout<<r->data<<endl; }

anyone knows what is the pblem with this code ?

this is the output Process returned -1073741819 (0xC0000005)

How can i delete a specific line from a text file using C programming?

How can i delete a specific line from a text file using C programming?

Don't copy it over to another file. Then delete original and rename new one to the same name as og

int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = &(r->data).at(i); rootAscii = rootAscii + int(x); //cout<<r->data<<endl; }

Do you check that r is not nullptr before running this code?

int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = &(r->data).at(i); rootAscii = rootAscii + int(x); //cout<<r->data<<endl; }

Also I'm a bit confused with this construction &(r->data).at(i) I wonder what type data is

Use sban

I don't care

I mean yeah, but I love deleting messages

int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = &(r->data).at(i); rootAscii = rootAscii + int(x); //cout<<r->data<<endl; }

Try assigning r->data to meaningful variable and use it instead. This will make the reason more clear

I mean yeah, but I love deleting messages

Lol

int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = &(r->data).at(i); rootAscii = rootAscii + int(x); //cout<<r->data<<endl; }

Maybe you are trying to do something like this!! — #include <iostream> #include <string> struct R { std::string data = "Test This String"; }; int main() { R *r = new(R); int rootAscii = 0; int curAscii = 0; for (int i = 0; i < (r->data).length(); i++){ char x = (r->data).at(i); rootAscii = rootAscii + (int)x; std::cout << ">> "<<r->data << std::endl; std::cout << "X: " <<rootAscii << std::endl; } return 0; }

your functions need to be declared or defined before you call them and malloc is declared in stdlib.h

Even after doing that it's not working
