The C++ compiler will implicitly (automatically) mark functions for inline expansion whenever you define a function within its own declaration. If functions are declared and defined separately (even in the same file) then they are not implicitly marked for inline expansion. To enable inline expansion for these definitions, you must explicitly mark the definition (not the declaration).
yes,we can make function inline
Structures in C and C++ differ in that C structures do not have an automatic typdef associated with them.
Use inline assembly instructions. Then compile your C++ program to produce the machine code.
Right angles are always 90 degrees. There is no need to calculate this; an angle is either 90 degrees or it is not. The following inline function is all you really need: inline const bool IsRightAngle(double angle) { return(angle==90.0); }
You use delete object in C++ to delete an object. You can also implicitly delete the object, if it is automatic type, by going out of local scope.
(C and Lisp, ... data type") was adopted by many later languages, such as ALGOL 68 (1970), Java, and C#. ... C++ has a separate Boolean data type ( 'bool' ), but with automatic conversions from ... "Report on the Algorithmic Language ALGOL 68
C++ programs won't compile if they contain compiler errors. The compiler will tell you precisely where the error is, and the type of error, unless the error is in a macro. The compiler cannot see macro definitions because they are inline expanded prior to compilation.
#include<iostream> using namespace std; inline int max(int a,int b) { return (a>b)?a:b; } int main() { int i1=3,i2=5; cout<<endl<<"Inline function says max is "<<max(i1,i2); return 0; } /* Usually when a function is called, the compiler goes to the particular piece of code and executes it. But in the case of inline functions, the code from the body of the function is effectively pasted at the point of call. inline functions are used when the body of the function is only a line or so.*/
b+b+b+c+c+c+c =3b+4c
c + c + 2c + c + c = 6c
b + b + b + c + c + c + c = 3b + 4c
