Hey all, I''ve got a pointer that points to a string of text.How can I output this string to txt file? Everytime I try to write it to file it showes me the adress and not the value. I know it''s noob question, but i wasn''t programming for a very long time. Thanks a lot.

1) is completely wrong, but I can see how 2) and 3) have some justification.

text is the value of the pointer - the address of the string literal. << just happens to be overloaded so that the string is printed, instead of its address. std::cout << (void*)text <<std::endl; would display the pointer value itself.

&text is the address of the text pointer - it''s a char**. There is some ambiguity as tho whether "the Address of the Text" referred to the text variable, or the string literal.

*text is the value of the pointee, not the value of the pointer.
