string crap = "abc:abd:aass";

Assuming this is std::string...

at the end of my string i want to place new characters like "xx"
so the final string looks like

string crap = "abc:abd:aassxx";

how to resolve this issue...

By adding them?

What have you tried?

crap.replace(crap.length(),1,"xx");

why not just

crap = crap + "xx";

?

#include <string>
#include <iostream>
using namespace std;

int main(void){
string a="abc";
a.push_back('.');
a+="def";
a=a+".ghi";
cout<<a<<endl;
return(0);
}

/*

std::string crap = "abc:abd:aass";

1. crap += "xx";
2. crap = crap + "xx";
3. crap += 'x'; crap += 'x';
4. crap.push_back('x'); crap.push_back('x');
5....

why not just

crap = crap + "xx";

?

Or ``crap += "xx";''? Or ``crap.append( "xx" )''? Or (for this
special case) ``crap.append( 2, 'x' )''?

I tend to use the first most of the time.

crap.replace(crap.length(),1,"xx");

Yes, it will. However, it would be more honest to write it this way:

crap.replace(crap.length(),0,"xx");

and even easier to write it this way:

crap += "xx";

as others have already pointed out.
