printnchars function, and use it to rewrite the triangle-printing program.

void printnchars(int ch, int n)
{
 int i;

 for(i = 0; i < n; i++)
  printf("%c", ch);
}

Here is the rewritten triangle-printing program:

#include 

int main()
{
 int i;

 for(i = 1; i <= 10; i = i + 1)
  {
  printnchars('*', i);
  printf("\n");
  }

 return 0;
}
