Type specifiers in declarations define the type of a variable or function declaration. Syntax type-specifier: void char short int long float double signed unsigned struct-
const int* bar(){ return new int[0]; } struct A{ double x; }; template <class T> T tFoo(const T& t){ return t; } bool func(){ return false; } struct Foo{ template <typename T, typename U> static decltype((*(T*)0) * (*(U*)0)) foo(const U& arg1, const T& arg2...
Thedecltype(expression)specifier is a type specifier introduced in C++11. With this type specifier, you can get a type that is based on the resultant type of a possibly type-dependent expression. decltype(expression) takesexpressionas an operand. When you define a variable by using decltype(expr...
C - Format Specifier for unsigned short int C - printf() Format Specifier for bool C - printf() Arguments for long C - printf() Specifier for double Is there a printf() converter to print in binary format? C - Nested printf() printf() Vs. puts() printf() Vs. sprintf() %d Vs....
In order to do that you can use el::Helpers::installCustomFormatSpecifier. A perfect example is %ip_addr for TCP server application;const char* getIp(const el::LogMessage*) { return "192.168.1.1"; } int main(void) { el::Helpers::installCustomFormatSpecifier(el::CustomFormatSpecifier("%...
