Write a C++ program to display Pascal’s triangle using the inline function.
The inline function inline A::T4Tutorials_pattern() 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 A::T4Tutorials_pattern().
Making inline means that compiler can replace the function definitions of inline A::T4Tutorials_pattern()with the place where this function is called obj.T4Tutorials_pattern();.
The compiler replaces the definition of inline functions at compile time instead of referring function definition at runtime.
