Then binary number system is converted to hexadecimal number system. Below is the step by step descriptive logic to convert octal to hexadecimal. Convert the given octal number to binary number system. Extract binary bits in a group of 4 bit starting from right side. Write the corresponding hexadecimal of extracted 4 binary bits. A full-featured IDE for C programming. Dev-C is an integrated development environment (IDE) for the C programming language. It presents a feature-rich environment, tools for writing and debugging, as well as a compiler to provide you with all the tools necessary to program software in C. The program is a fork of the Bloodshed Dev-C.
When developing cross-platform terminal applications or using terminal output for logging or debugging, it's useful to color the output in order to not lose the overview.
This article shows how to color the terminal output on various platforms.
Linux
On Linux, you can change the current foreground and background color by writing special character sequences into the output. Write the ESC escape character (octal '033', hex x1b), followed by an opening square bracket [. The color definition will follow next, termniated by a lowercase m.
In order to make the text color red (number 31), you can write ' 033 31m' which will make any following output red. If you want yellow text (33) on blue background (44), you write ' 033 31;44m'. To reset everything back to the default colors, you write ' 033 0m'. The terminal-colors.d manual gives you an overview over the available codes. Assigning the Hexadecimal number in a variable. There is no special type of data type to store Hexadecimal values in C programming, Hexadecimal number is an integer value and you can store it in the integral type of data types (char, short or int). Let suppose, we have two values in Hexadecimal '64' (100 in Decimal) and 'FAFA' (64250 in Decimal).
The color definition is a series of numbers, separated by semicolons. In order to make the text color red (number 31), you can write '033[31m' which will make any following output red. If you want yellow text (33) on blue background (44), you write '033[31;44m'. To reset everything back to the default colors, you write '033[0m'.
The terminal-colors.d manual gives you an overview over the available codes.
Windows
On Windows, coloring the terminal output, works a bit different. Instead of writing special character sequences into the output, you have to call special functions from the windows library. #include <windows.h> in order to access the Windows functions. This provides the SetConsoleTextAttribute() function that can be used to color the text. You also need to get a handle to the stdout console using GetStdHandle(STD_OUTPUT_HANDLE).
The following code shows how to color the text red and yellow on blue background:
Unlike Linux, where each foreground and background color has an individual number, you work with the red, green and blue channels on Windows. As you can see with yellow, it's a combination of red and green for example.
