String processing: word replacement

[anhtt]

Hi,

I am a newbie in C++. I wonder if there is a standard lib function do
this sort of thing:

string str = " I am XXX, hence I am YYY";

str = replace(str, "XXX", "lazy"); // str now is " I am lazy, hence I
am YYY"
str = replace(str, "YYY", "zzzzing"); // str now is "I am lazy, hence I
am zzzing"

Many Thanks!

Not that I know of. You have to use string::find in combination with
string::replace to replace a substring like that. Make yourself a helper
function that does it, not very hard.

See http://www.boost.org/doc/html/string_algo.html

#include "boost/algorithm/string/replace.hpp"

using boost::algorith m;

....

string str = " I am XXX, hence I am YYY";

replace_first(s tr, "XXX", "lazy"); // str now is " I am lazy, hence I am
YYY"
replace_first(s tr, "YYY", "zzzzing"); // str now is "I am lazy, hence I am
zzzing"

Thanks, the link is very useful, I am not aware of Boost. Quite a
newbie in C++.

Newbie or not, I find boost indispensable. You'll probably find that for
many common tasks, boost provides the facilities that you would have had to
develop on your own. Most of the libraries do not require you to build
boost. You can just download and extract to something like
'C:/boost/boost_1_32_0'. Then add this to your include path. If you use this
approach, handling updates is much simpler.

Have fun.
