Re: Split char* using pointers and strchr 12 Years Ago by Ancient Dragon you have to allocate memory (see malloc or new) for nameBuffere before you can copy something to it. Also, I don't see any \* in the example you posted -- maybe because DaniWeb editor deleted them.

First, don't call strlen() in the condition of a loop because it's inherently inefficient. strlen() is a function that itself contains a loop, so when you say this: for (int i = 0; i < strlen(word); i++) { ... } It's roughly equivalent to this: … Re: Why is this strchr program a segfault? 12 Years Ago by HelloJarvis Great, thanks! A quick fix to the while loop got it right back up and running! Also, about the toupper and such, I omitted that code, so not to worry, it is being converted to uppercase. Re: Problems working with strchr 19 Years Ago by Dogtree You've pretty much checked off everything on the "don't do" list of basic C.
