A do-while loop always runs at least once, even when its condition is false the first time. This behaviour is possible because C# evaluates the loop condition after the loop’s body, and not before. In plain English, its description is: “do this, and then repeat while this condition stays true”. To make a do-while loop we use the do keyword.Here's the basic syntax for a do while loop: do {. // body of the loop. } while (condition); Note that the test of the termination condition is made after each execution of the loop. This means that the loop will always be executed at least once, even if the condition is false in the beginning. This is in contrast to the normal while loop ...The reason your inner loop only executes once is because you initialize j to 0 outside the loop and then never reset it again. After it runs the first time the value of j is 10. It will never be less than 10 again. A better way to do this is to use a for loop: for (int i … Setting the color can be done using a color picker in Studio. To do so, left click inside the () next to fromRGB.
