Create a C source le and copy the following function de nition into it:
void triangle(unsigned width)
{ unsigned i, j;
i = 0; while (i <= width) { j = 0; while (j < i) { putchar('*');
++j; } putchar('\n');
++i;
}
}
Add a main function that calls triangle() with a number of your choosing, and complete the source le such that you can compile and execute your program.
2. (3 points) Rewrite triangle() to use for loops instead of while loops.
3. (3 points) Write a version of triangle() called v_triangle() that prints the triangle upside-down, with themaximum length line at the top.
4. (3 points) Write a version of triangle() called h_triangle() that prints the triangle such that the right side isvertical. That is, h_triangle(5) should print
*****
****
***
**
*
5. (3 points) Create a program that can print any of the three triangles described above, based on itscommand-line arguments. Use atoi() to convert the rst argument from a string to an integer: this will be the width of the triangle. If no second argument is provided, use triangle(). If the second argument is "v", use v_triangle(). If it is "h", use h_triangle().
Your program should return EXIT_SUCCESS from main for normal operation, or EXIT_FAILURE if given incorrect/inappropriate arguments.
