The look and feel of wxDev-C is very similar to that of Visual C, so if you're used to one, the switch to the other will be without too much problems. In the end, I'd suggest to give both of them a try, and see which one suits you best. B) Which function would be the best to write and read the correct format fomr and to HD-Files? I used to apply fprintf with formatted strings to read full lines of a file with known structure and directly obtained the desired variables. I copied the source code from a DOS prog and DEV C compiles but reads only shit!

The double is a fundamental data type built into the compiler and used to define numeric variables holding numbers with decimal points. C, C++, C# and many other programming languages recognize the double as a type. A double type can represent fractional as well as whole values. It can contain up to 15 digits in total, including those before and after the decimal point.

Uses for Double

The float type, which has a smaller range, was used at one time because it was faster than the double when dealing with thousands or millions of floating-point numbers. Because calculation speed has increased dramatically with new processors, however, the advantages of floats over doubles are negligible. Many programmers consider the double type to be the default when working with numbers that require decimal points.

Double vs. Float and Int

Other data types include float and int. The double and float types are similar, but they differ in precision and range:

  • A float is a single precision, 32-bit floating-point data type that accommodates seven digits. Its range is approximately 1.5 × 10−45 to 3.4 × 1038.
  • A double is a double-precision, 64-bit floating-point data type. It accommodates 15 to 16 digits, with a range of approximately 5.0 × 10−345 to 1.7 × 10308.

The int also deals with data, but it serves a different purpose. Numbers without fractional parts or any need for a decimal point can be used as int. Thus, the int type holds only whole numbers, but it takes up less space, the arithmetic is usually faster, and it uses caches and data transfer bandwidth more efficiently than the other types.

Program comments are explanatory statements that you can include in the C++ code. These comments help anyone reading the source code. All programming languages allow for some form of comments.

C++ supports single-line and multi-line comments. All characters available inside any comment are ignored by C++ compiler.

C++ comments start with /* and end with */. For example − Audio evolution auto tune.

A comment can also start with //, extending to the end of the line. For example −

When the above code is compiled, it will ignore // prints Hello World and final executable will produce the following result −

Within a /* and */ comment, // characters have no special meaning. Within a // comment, /* and */ have no special meaning. Thus, you can 'nest' one kind of comment within the other kind. For example −
