c++ quick reference / c++ cheatsheet Based on Phillip M. Duxbury's C++ Cheatsheet and edited by Morten Nobel-Jørgensen. The cheatsheet focus is both on the language as well as common classes from the standard library.
Instead of a "flat" sheet of choices, I'd prefer one simple rule (esp. to teach beginners): use const lvalue reference to objects by default, unless there are reasons to use other types instead... plus one caveat: avoid non-reference decayable types (function types, cv-qualified object types or array types) and rvalue references to functions ...
A function that returns a value must have a return statement. The data type of the return value also must match the method’s declared return type. On the other hand, a void function (one that does not return anything) does not require a return statement. #
C++ Syntax Cheat Sheet. Preface. Since the C++ language varies so heavily between versions (e.g. C++0x, C++11, C++17, etc.), I will preface this cheat sheet by saying that the majority of the examples here target C++0x or c++11, as those are the versions that I am most familiar with.
void bar(int i) { // bar definition std ::cout << "Bar: " << i << " \n";} int main() { // main definition foo(); // calls foo function bar(2); // calls bar with 2 return 0;} All programs must have a main function. This is the first function that gets called. All functions except main() should have a
