problem:
I want to pass a string with the size from the main function but don't know how.Can someone show me how I can do it.

Answer 1

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.

Answer 2

You could try this as well

@Martin Thanks a trillion ...

Answer 4

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.
