1. Don't post photos, use pastebin or at least.. make a screenshot 2. If you have a compilation error, you can past the error here, so we won't guess what the compiler told you 3. oh my god.. these indentations, my eyes are bleeding when I try to read this code

Use sizeof operator to get array size and then fit it in termination of loop

Jussi

Sorry for offtopic, but is anyone proficient in regex here?

Asdew

Just ask your question.

Asdew

Like, for example, I am definitely not proficient, but I might be able to help.

I know some regex

Nameful

Not great though

Jussi

May I PM you?

Nameful

I would say ask here, but I'm not sure it's allowed

Nameful

I suppose you could use regex in C++ though?

Asdew

Ask here. If you're scared, just make some C++ program using Regex and say the Regex is for that program.

hello, I iam little bit in struggle. I don't get the right solution. In the text.txt file are names and they are separated by spaces and tabs. I can only search with argv after the first word in the file and get the right solution. Can someone pls help me, who knows how I move to the next word FILE *fp = fopen("text.txt", "r"); single = fscanf(fp, "%s", input); fund = strstr(input, argv[1]); if(fund != NULL) {     printf("1"); }  Thank you very much

Can you use C++ or is it only C?

std::string str="abc",r; std::stringstream s; s<<str[0]; s>>r; A way to convert a single char to string. Why does the stream puts str[0] into r by doing s>>r ? I though after s<<str[0], r = s.str() should have been done.

Both are correct ways

Pavel

In one case you pull one value, in another you form a string out of the stringstream buffer if there's one value, the result is the same

ok so after s>>r nothing is left in stream but on the other case stream still contains "abc". Right?

Dima

yes they are characters

Dima

everything in string is a character

kaptan

thanks

kaptan

i couldnt write a code for this ,can somebody help me?

kaptan

i know this is easy but i m new at programming so it is actually hard for me

Anonymous

To not be a beginner you have to write it yourself

kaptan

you are right :( , well i dont actually understand the question , if our string is actually numbers , and it says length of the string , what am i suppose to find as a length , i mean let s say my string is 16 , is the length i should find is 2 ?

Your function is given a string a length of that string, you don't need to find length yourself

Nope. Inner string is still "r", but file pointer is on eof

Jens

The answer helped me, thank you. But I have one more question. The problem is, if I search for "pattern" with "strstr", it also counts the results "patternman" "patternwoman". But it should only look for exactly this one word.

You need regexp then. Or strstr with offset in cycle

anyone pls explain why ~0 is -1 , not 1

Григорий

~ is operation that inverts bits. 0 is 00000000 (binary), ~0 is 11111111(binary), 11111111(binary) is -1. 1 is 00000001(binary).

11111111 is -1 ? how ?
