The document contains code snippets showing the use of variables, operators, control flow statements like if-else and switch-case, and input/output statements like printf and scanf in the C programming language. It defines variables, performs basic math operations on variables, and prints the results to the screen. Control structures like if/else and switch/case are used to check conditions and print corresponding outputs. Input is taken using scanf and output displayed with printf.
