How do you comment out multiple lines in C?
The compiler will assume that everything after the /* symbol is a comment until it reaches the */ symbol, even if it spans multiple lines within the C program. You can create a comment that displays at the end of a line of code. In these examples, the compiler will define a constant called AGE that contains the value of 6.
