hello,
i have a problem with strlen. I have written this:
for(y=13,z=0; cInBuf!=' ';y++)
{
cBuf=cInBuf;
z++;
}
len = strlen(cBuf);
out=len/2;
fprintf(outfile,"F%i",out);
If strlen is e.g. 22, it write F22. I want to write F2F2.
How can i do this?... (5 Replies)
For example if i have the piece of code as follows:
CountryName = (char *)malloc((strlen(CountryName)+1)*sizeof(char));
memset(CountryName, 0, strlen(CountryName)+1);
CountryName = SOME VALUE
Now how do i free the memory after use of this code???? :confused: (3 Replies)

In a declaration, I have:

const int comment_end_len = strlen(comment_end);
When I compile, I get the warnings:

Hi all,
We use strlen() fun provided by library to find the length of a string.
Looking inside of it, it has some different mechanism to find the length of string.
Normally, we scan the string byte by byte until the '\0' character. It takes a logn time to count length.
The Library strlen()... (2 Replies)
