Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The writer intended to type c = a + 8 / b + 1; and : they pressed comma instead of a /."

A block of code is set as follows:

inline auto mult(int lhs, int rhs) -> int 
    { 
        return lhs * rhs; 
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

if (op == ',' || op == '.' || op < '+' || op > '/') 
    { 
        cout << endl << "operator not recognized" << endl; 
        usage(); 
        return 1; 
    }

Any command-line input or output is written as follows:

C:Beginning_C++Chapter_02cl /EHsc calc.cpp

Bold: New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "The calling convention of the function determines whether the calling function or the called function has the responsibility to do this."
