Write a program that receives a string with a maximum length of 100 characters from the user and sends it to the ChgStr function, this function removes the spaces in the string and counts the number of k letters in the string. This number as well as the new string will be printed in the main function after removing the space. * C language Friends, anyone knows this?

I'm in hurry, I'll be grateful if anyone knows and helps me.

Is that a homework or an assignment?

If I use malloc/realloc and execvp successfully replaces the process a further free() will never be called Why do you care? As a part of execvp, the memory image of the process is replaced completely. How does it matter whether the array allocated in original forked child process is freed or not. If the args array was built in the parent process, then you should still free it in the parent process.

That is a question of final exam of semister, why ?

Goodluck

Hi, does anyone know why im getting the error "expected declaration or statement at the end of input"? Here's the part of my code: for(i=0; i<num; i++) { fprintf(fp, "%d %s %s %s %s %s %s\n",sPui[i].puiid, sPui[i].name, sPui); }

Should be something like this I guess Int main (){ Int program [100]; printf(“ Enter up to 100 characters ”); scanf(“%d”, &program); printf(“%s”, program); return 0; }

not good solution

What’s the right solution

getting input as int seems weird

What data type do you think is perfect for getting the value?

as per groups rules, asking home homeworks and assigments is forbidden

How is it forbidden that you're already discussing for a better solution !?

And using array won’t do the job either For example: using array goes like this . datatype Array_name [ here u pass in values eg 1,2,3,4] datatype = Int Char Float Double Array_name = program Values = 1,2,3…

it is forbidden to ask for them: • You should not ask exams/homework/interviews solutions. This will get you banned.

Ok.

you have read and agreed to the rules before posting, so don't act surprised

Are you trollin ?

But they only display the ascii values

Unicode chars also represented as bytes

Actually, Unicode characters are two bytes long each.

Yes wchar_t is 16 bits

What does wchar_t mean? Are there other types like that one?

You don't know wide characters ?

Yes, I do, but what does the t mean?

indicating the type is typedef like uint32_t, size_t

OK. Does t mean that it’s a custom type?

The ISO Commitee typedef-ing stuffs with *_t suffix

Suffix. Not prefix.

Sorry, suffix

Living, would you mind telling me how to register a keystroke event in C++?

Maybe that's kind of specific OS API ?

In plain old C, then?

On Windows maybe using win32 APIs or using termios stuff on *nix

Can anybody please help me with this question

How is registering a keystroke different from cin or scan()?

They interact with the console first then the console goes to send input to the buffer,

Whereas keystrokes go straight to the buffer?

Not really, the consoles/terminal processing the user input first

how to cast pointer to string? for example: int * ptr; // = 0xadf51ff8fc // after cast std::string ptr_str; // = "0xadf51ff8fc"

Incompatible type, std::string is not scalar types

how std::cout convert pointers to text then 🤔

void stringcopy(string s) { string str; int i, j; for (i = 0; s[i] != '\0'; i++) { str[i] = s[i]; } str[j] = '\0'; cout << "string copied!!!\n" << str; }

void stringcopy(string s) { string str; int i, j; for (i = 0; s[i] != '\0'; i++) { str[i] = s[i]; } str[j] = '\0'; cout << "string copied!!!\n" << str; }

Hi everyone I have a question I want to take a long string as an input and then split it according to spaces The length of string is not clear Any idea ?
