 The project which you will be working on today contains the `cropSwap` function that implements the functionality of exchanging the pixels contains in two congruent rectangles within an image. Its prototype is: 
 
-```
-void ImageScrambler::cropSwap(QImage &img, int x0, int y0, int x1, int y1, int width, int height );
-```
+`void ImageScrambler::cropSwap(QImage &img, int x0, int y0, int x1, int y1, int width, int height );`
+
 
 Its parameters are:
 * `img`: reference to the image that we wish to modify (an object of the `QImage` class)
 
 For example, if we wish to exchange the pixels of the upper and lower halves of an image *P* with width 100 and height 150, we invoke the function:
 
-```
-cropSwap(P, 0, 0, 0, 75, 100, 75 );  
-```
+`cropSwap(P, 0, 0, 0, 75, 100, 75 );`
