is there a C/C++ function that I can copy a char array of a pointer to another char pointer but instead of defining a numerical stopping point (like strncmp), is there one that will stop copying like say at the NULL character?<br/>thanks!!

What is the use for ptr-to-ref?CG article describing ( http://www.dev-archive.com/cpp/cpp/cpp_mfc/pointers/article.php/c4089/#3) I found this article, but when it comes to pointer to reference *& it is shall we say unprecise in the descriptions and the purposes of its use.It appears to be used just l...

hi! i needed to know whether anyone knew how to code this so that it will skip over the white spaces in a file. mdefn is a string and it is reading from a file with a line of whitespaces. so basically what it is doing is just retaining the last word before the # sign which is my sign to end. I canno...

Hi all, I am writing yet another recursion program for an assignment. In this one we are supposed to recursively count the number of domino tiles that an cover a certain board.

Hi guys:I want to write the function ultoa(unsigned long l, char* pStr, int base), which is to convert any unsigned long number to string of base "base".

I am using 'cin' to grab string from command prompt into a char* array. The char* is initialized using "new". It seems to work but is it good practice? Is there any details such as mem corruption that is going wrong here? If so, how can I fix this? Thanks!

Do local variables leave scope when the function is done? <br/>By using the MS VS 2k5 debugger, it seems that they do but I want to verify.<br/>Thanks!
