C++ has nothing to do with pixels. Your question may be related with 'Windows programming' or 'DOS programming' or 'X Window System programming'.
Draw a circle with its center at the origin and a radius of 3.
Draw circle.Draw "plus sign" + on top of circleDraw "times sign" x on top of circlepresto eight cake slices of circle.Simply place the plus sign in the circle so the plus sign touches the edges, then overlap the times sign on the plus sign. It should give you eight lines in the circle, which are eight slices.

TO create a compass rose, you need 4 lines going straight in the shape of a plus sign. the top on is north the bottom is south. to label west and east when you read them across they should spell we. Then draw a smaller x through the plus so there is a lone between each line of the pluss. the one between south and east(lower right) is south east because they intersect.
A quarter of a circle plus an eighth of a circle is what percent of a circle?
A square will always be larger than a circle with the same diameter. Draw a square, then draw a circle that fits inside the square exactly (that is, each of the four points shared by the two shapes exactly bisect each line of the square). The square contains the entire circle, plus all the extra area in the corners.
In order to compare images pixel by pixel, both images must be uncompressed bitmaps of the same size, dimensions and colour depth. If you're looking for an exact match, then you simply compare the pixels in tandem (you can treat both images as being an array of int to speed up the process).
Sorry, it's impossible to draw with a keyboard!
75 Percent.
You don't: the C and C++ languages do not have any built-in graphics tool. Further, it is impossible to draw a concentric circle. Multiple circles are concentric when they share the same center.In C or C++, graphic functions such as the drawing of lines, rectangles or circles are provided through third party libraries, or through wrappers which provide access to the operating system's graphics functions.
