'cout' Was Not Declared In This Scope
Answer : Put the following code before int main() : using namespace std; And you will be able to use cout . For example: #include<iostream> using namespace std; int main(){ char t = 'f'; char *t1; char **t2; cout<<t; return 0; } Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/ Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std; at the top of your code. For detailed correct approach, please read the answers to this related SO question. Use std::cout , since cout is defined within the std namespace. Alternatively, add a using std::cout; directive.
