formatting text output
I want to output a string but i want to limit width of the column how do i do this?
string = "hello this is a test for width"
I want it to look like this:
cout << string;
hello this
is a test
for width
I know cout.width (5) will start 5 over but what will stop it at 15 plus i want it to wrap the word to the next line if the whole word won't fit on that line.

beat me by minute...
char *string = "hello this is a test for width";
char *s0 = string;
char *s1;
while( strlen(s0) > 10 && (s1 = strchr(s0,' ')) ){
char *s2;
while( (s2 = strchr(s1+1,' ')) && s2-s0 <= 10 ){ s1=s2; }
*(s0 = s1) = '\n';
}
char *s0 = string;
char *s1;
while( strlen(s0) > 10 && (s1 = strchr(s0,' ')) ){
char *s2;
while( (s2 = strchr(s1+1,' ')) && s2-s0 <= 10 ){ s1=s2; }
*(s0 = s1) = '\n';
}
That's about half the length I would have come up with!

That works but I need it to start at certain amount of spaces over aswell. I tried a few things but I could only get the first part over.
Ex.
hello this
is a test
for width
Any suggestions?

How would I do this if I want to ask the user for the string? When I tried this it would only put one word per line until the last line which it had two.
Do you need help implimenting that?
