    C :

    #include <stdio.h>
    void main ()
    {
    	int n;
    	scanf("%d",&n);
    	int i;
    	for ( i = 1; i<=n; i++ )
    	{
    		if(i<=n-1)
    		{
    			int k;
    			for(k=1; k<=n-i; k++)
    			{
    				printf(" ");
    			}
    			printf("*");
    			int j;
    			for(j=1; j<=2*i-3; j++)
    			{
    				printf(" ");
    			}
    					if(	i-1!=0	)
    			{
    				printf("*");
    			}
    				printf("\n");
    			
    		}
    		if(i==n)
    			{
    				int x;
    				for( x=1; x<=2*n-1; x++ )
    				{
    					printf("*");
    				}
    			}
    	}
    	
    	
    	
    	
    	
    	
    
    
    }
    

    C++ :

    #include <iostream>
    using namespace std;
    
    int main(){
        int i,j,n;
        cin>>n;
        for(i = 1;i <= n;i++){
        	for(j = 1;j <= n - i;j++){
        		cout<<" ";
    		}
    		
    		for(j = 1;j <= 2 * i - 1;j++){
    			if(i == 1){
    				cout<<"*";
    			}else if(i == n){
    				cout<<"*";	
    			}else{
    				if(j != 1 && j != 2 * i - 1){
    					cout<<" ";
    				}else{
    					cout<<"*";
    				}
    			}
    			
    		}
    		
    		cout<<endl;
    	}
    }
    
    

    Python :

    n = int(input())
    i = 1
    while i <= n:
        j = 1
        while j <= n - i:
            print(" ",end="")    
            j += 1
        k = 1
        while k <= 2*i-1:
            if k == 1 or k == 2*i-1 or i == n:   
                print("*",end="")
            else:
                print(" ",end="")     
            k += 1
        print("")
        i += 1
