how to implement this ?

[madeofdata]

what is the code to implement this function?
countCharInText
Counts the frequency of a character in a text
the prototype is
int countCharInText (char* text, int size, char toCount);

[boxfish]

Loop through alll the characters in text and check whether each one is equal to toCount. We can't give you the code for it because you're supposed to do the assignment.
Hope this helps.

this not an assignement I am looking for the code because I need to review for my test and I am not able to impelment the function..so please if you can help me a bit more....

[boxfish]

Okay, here's pseudocode:

Set a counter variable to zero.
For each character in text:
    If it's equal to toCount:
        Increment the counter variable.
Return the counter variable.

I hope this is more helpful. :-)

but there is a problem , for the space and new lignes what should I do?

What makes you think there's anything special about space and new line characters? Either the next character in the string matches or it doesn't.

I suggest you post a source code snippet that steps through each character in the string (the 'for' loop in boxfish's pseudocode). No need to do anything in the loop right now. Based on your questions in this thread and in your myStrCmp thread I think you might be having trouble with this task.

this is my function :
int countCharInText (char* text, int size, char toCoun){
char c = 0;
int i = 0;
int frequence = 0;

for(i = 0; i < size-1; i++)
{
if(text[i] == toCount)
frequence++;
}
return frequence;
}

is it correct ?
+ how the main function should be knowing that I cannot use a scanf and that the sentinel is a "."(a dot)

It would be helpful if you used code tags around your code. Put [CODE] before the code and [/CODE] after it, so it shows up in a code box and the indentation isn't wrecked. Thanks. Anyway, yes, that function looks right, except for that you don't need to declare c, and the condition for your for loop seems to skip the last letter. I'm not sure about the main function; maybe someone else who knows more about c i/o can help with that.
Good luck on your exam.

is it correct ?

If your input text is a null-terminated string then you don't need to pass in the size -- keep comparing until you find the null character ('\0').
