Write a c++ program to find out the sum of an A.P. series by using the inline function.
Write a c++ program to find out the sum of an A.P. series by using the inline function.
The inline function inline T4Tutorials_AP_Series::T4Tutorials_AP_Series_Function() helps to increase the execution time of a program. The programmer can make a request to the compiler to make the inline function as inline T4Tutorials_AP_Series::T4Tutorials_AP_Series_Function().
Making inline means that compiler can replace the function definitions of inline T4Tutorials_AP_Series_Function()with the place where this function is called object.T4Tutorials_AP_Series_Function();.
The compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime.
