Section 2.7, Question 6 - "Which of the following are keywords in C?"

[ghost]

If there are any errors in my answer, feel free to correct them below.

Apart from b) If, c) main and d) printf, the rest of the options are all keywords.
Explanation:

1. If is not the same as if. Since C is a case-sensitive language, the latter which is a keyword, is not recognized to be the same as the former.
2. try declaring a int variable called main with some value, and try printing it on the screen. It has been hard-coded to be called by the operating system while executing a C program.
3. printf is a part of the standard input/output library stdio.h. You can create your own variable called printf, although you can no longer use the printf() function.

1. Where is main stored & is main a keyword? I do know that main() is a method but I am asking about "main"
2. Is printf a keyword?
