C++ program of inline function to display a pattern for a number of rows

Write a C++ program of inline function to display a pattern for a number of rows using a number which will start with the number 1 and the first and the last number of each row will be 1. The pattern is as follows:

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.

#include<iostream>
#include<conio.h>
using namespace std;
class A
{
	public:
	int i,j,k,l,n;
	public:
		int T4Tutorials_pattern();
	};
	inline A::T4Tutorials_pattern() 
	{
		cout<<"enter num of rows:";
		cin>>n;
		for(i=1;i<=n;i++)
		{
	    	for(l=1;l<=n-i;l++)
	     	{
			cout<<" ";
			}	
			for(j=1;j<=i;j++)
			{
			cout<<j;	
			}
			for(k=i-1;k>=1;k--)
			{
				cout<<k;
			}
			cout<<endl;
		}
	}
int main()
{
	A obj;
	obj.T4Tutorials_pattern();
		}

#include<iostream>

#include<conio.h>

using namespace std;

class A

{

public:

int i,j,k,l,n;

public:

int T4Tutorials_pattern();

};

inline A::T4Tutorials_pattern()

{

cout

<<"enter num of rows:";

cin>>n;

for(i=1;i<=n;i++)

{

for(l=1;l<=n-i;l++

)

{

cout<<" ";

}

for(j=1;j<=i;j++)

{

cout<<j;

}

for(k=i-1;k>=1;k--)

{

cout<<k;

}

cout<<endl;

}

int main()

{

A obj;

obj.T4Tutorials_pattern();

}
