C++ Exercises: Display the pattern like right angle triangle with number increased by 1

Sample Solution:

C++ Code :

#include <iostream>
#include <string>
using namespace std;

int main()
{
   int i,j,rows,k=1;
    cout << "\n\n Display such a pattern like right angle triangle with number increased by 1:\n";
    cout << "---------------------------------------------------------------------------------\n";
    cout << " Input number of rows: ";
    cin >> rows;
   for(i=1;i<=rows;i++)
   {
	for(j=1;j<=i;j++)
	   cout<<k++<<" ";
	cout<<endl;
   }	
}

Sample Output:

 Display such a pattern like right angle triangle with number increased by 1:                                                                 
---------------------------------------------------------------------------------                                                             
 Input number of rows: 4                                               
1                                                                      
2 3                                                                    
4 5 6

C++ Programming: Tips of the Day

Using C++ library in C code

You will need to write an interface layer in C++ that declares functions with extern "C":

extern "C" int foo(char *bar)
{
returnrealFoo(std::string(bar));
}

Then, you will call foo() from your C module, which will pass the call on to the realFoo() function which is implemented in C++.

If you need to expose a full C++ class with data members and methods, then you may need to do more work than this simple function example.
