Not sure what you want to do, but the implementation of String(const char*) is wrong because len is undefined. You can get the len with the following: len = 0; const char* p = str; while(*p++) ++len; You can also initialize your data in the loop and remove the memcpy() if you want. This way, the calling of String("Text") will Initialize data and len correctly.

The question given was: 10.6 Implement a String class. Each object of this class will represent a character string. Data members are the length of the string and the actual character string. In addition to constructors, destructor, access functions, and a print function, include a “subscript” function.
