Stopping condition on a recursive function - Haskell
string,function,haskell,if-statement,recursion
Your code doesn't handle the case where a line is shorter than the maximum length. This is somewhat obscured by another bug: n is decremented until a whitespace is found, and then f is called recursively passing this decremented value of n, effectively limiting all subsequent lines to the length...
Decremented value called in the recursion in Haskell
string,function,haskell,recursion,parameters
Yes, once you call again f with a new value of n, it has no way to reference the old value of n unless you pass it explicitly. One way to do it is to have an internal recursive function with its width parameter, as you have, but that can...

Use cast_number/*char*/ = (char) help_variable_remove_pv + '0'/*int*/; instead of cast_number/*char*/ = (char) help_variable_remove_pv/*int*/; A character and an integer somewhat are different. This means that '0'(character 0) and integer 0 aren't equal. You'll have to add 48 (ASCII value of '0') to 0 to get the integer value of '0'. See...
