3+ Incredible Tips on How To Color A Variable In C

Within the C programming language, you should use the printf() operate to print textual content and variables to the console. The printf() operate takes a format string as its first argument, which specifies how the output needs to be formatted. The format string can include placeholders for variables, that are represented by % characters adopted by a sort specifier. For instance, the next code prints the worth of the variable ‘x’ as an integer:

printf(“The worth of x is %dn”, x);

It’s also possible to use the printf() operate to print variables in colour. To do that, you have to use the %c escape sequence, adopted by a colour code. The next desk lists the colour codes that you should use:

For instance, the next code prints the worth of the variable ‘x’ in crimson:

printf(“33[31mThe worth of x is %d33[0mn”, x);

It’s also possible to use the printf() operate to print textual content in colour. To do that, you have to use the %s escape sequence, adopted by the textual content you need to print. For instance, the next code prints the textual content “Hey world” in crimson:

printf(“33[31mHello world33[0mn”);

Shade coding could be helpful for debugging functions, or for merely making your output extra visually interesting.
