If you read and convert ‘multibyte’ or Unicode strings in the wrong way you may have a loss of characters, because of Unicode string-to-string or wstring to string operations. As a result, we have different string types. This started with string, then wstring, u16string, u32string, UnicodeString, etc. Unicode string literals are the most broadly compatible strings that we can use in C++.

Using the Canvas property and drawing methods in C++ Builder, it is simple to draw images on Bitmaps.Canvas CPP may be utilised in FMX and VCL programmes. For objects that must render their own graphics, canvas offers an abstract drawing surface. TCanvas offers methods, events, and properties that help with image creation. Canvas needs the BeginScene() and EndScene() methods in C++ Builder FireMonkey applications in order to change that memory area more quickly. Any component's Canvas property can be used. All of the samples about canvas of bitmaps . Visit the website. https://learncplusplus.org/quickly-learn-how-to-use-canvas-drawing-in-c-on-windows/

Thinking of how to make C++ in Milisecond timer? he challenge is, how can we calculate speed of our function in C++ when they might only take a couple of milliseconds? An execution time of one hundred milliseconds sounds fast – but it’s not great when that routine has to be called many thousands of times. Here the best way is calling the same function n times. i.e. 1000 or 1 Million times, so we can exactly calculate the speed of that function. This may help us to improve our functions, algorithms and / or methods to use.
