so that they cannot be accessed from the class’s non-member functions. However, in certain situations, there is a need to access the private data members of a class by a function that is not the class member. It can be achieved by making the non-member function as a: friend function...
Syntax Of Function Prototype In C++: returnType functionName(parameterType1 parameterName1, parameterType2 parameterName2, ...); return_type:This specifies thedata typeof the value that the function will return when it is executed. It indicates the type of the result produced by the function. ...
even if the statement expression is completely constant its self (i.e., can be fully evaluated at compile-time and otherwise passes the __builtin_constant_p() test). Further, they cannot be used outside of a function body. Hopefully, GCC will amend these shortcomings soon and allow ...
In C, we have used Macro function an optimized technique used by compiler to reduce the execution time etc. So Question comes in mind that what’s there in C++ for that and in what all better ways? Inline function is introduced which is an optimization technique used by the compilers ...
See also my question here: What is a call to char() as a function in C++? So, let's recap: : root(sz) in the constructor is like constructing vector<int> root(sz);, which creates sz number of elements in the root vector, each with initial value int(), which is the syn...
Functions accept structures as their arguments in a similar way as they accept any other variable or pointer. To pass a structure to a function, a structure variable is passed to the function as an argument. A structure variable can be passed to a function as an argument in the following ...
