This document discusses looping statements in C programming like break, continue, and preprocessor directives. It explains that break terminates loops immediately, continue skips statements, and preprocessor directives beginning with # instruct the compiler on pre-processing like text substitution before compilation. Preprocessor directives must start in the first column with # and include commands like #include, #define, #ifdef, and more.

- 2. Break Statement • The break statement terminates the loops (for, while and do...while loop) immediately when it is encountered. • The break statement is used with decision making statement such as if...else. Syntax: Break; Copyrights By Tanveer Malik

- 4. Continue Statement • The continue statement skips some statements inside the loop. The continue statement is used with decision making statement such as if...else. Syntax: continue; Copyrights By Tanveer Malik

- 6. Preprocessor Directive • The C Preprocessor is not a part of the compiler, • It is a separate step in the compilation process. • In simple terms, a C Preprocessor is just a text substitution tool and it instructs the compiler to do required pre-processing before the actual compilation. • We'll refer to the C Preprocessor as CPP.

- 7. Preprocessor Directive • All preprocessor commands begin with a hash symbol (#). • It must be the first nonblank character, and for readability, a preprocessor directive should begin in the first column. • The following section lists down all the Copyrights By Tanveer Malik
