The easiest way to read formatted input in C++?

Question

Is there any way to read a formatted string like this, for example :48754+7812=Abcs.

Let\'s say I have three stringz X,Y and Z, and I want

Answer 1

You can use scanf. It is not overly C++ - ish, but it does the trick with remarkably few lines of code:

char a[101], b[111], c[121];
sscanf(":48754+7812=Abcs", ":%100[^+]+%110[^=]=%120s", a, b, c);
string sa(a), sb(b), sc(c);
cout << sa << "-" << sb  << "-" << sc << endl;

The idea is to specify the characters accepted by the strings that you read using a very limited regular expression syntax. In this case, the first string is read up to the plus, and the second string is read up to the equals sign.
