It is possible to return a String from a function?
If yes, how?
I'am trying to return a full string from this function:
But this dont work... he just returns 1 char, not all the string.Code:char substr(char *str, int start, int end) { int i,j; char strCp[100]; for(i = start, j = 0; i <= end; i++,j++) strCp[j] = str[i]; strCp[j] = '\0'; return *strCp; }
To return a string, make the return type char *. But in this case it won't work because your string is local, when the function returns it goes away so a pointer to it is invalid.

My best code is written with the delete key.
Hmm, just assigning to an global variable the value of my local variable? or this isnt good too?
You could strcpy() your local string to a global one if you wanted, in which case you wouldn't have to return it. However, use of global variables should be kept to a minimum.
It is better to pass the function a pointer to a pre-allocated buffer, along with the size of the buffer. The function can then write data directly to it.
When all else fails, read the instructions.
If you're posting code, use code tags: [code] /* insert code here */ [/code]
Thanks for the help
