Flashcards

'C' Language Structure

The way a 'C' program is organized, it's built using functions as blocks, which are independent units of code.

Keywords in 'C'

Reserved words with predefined meanings in the 'C' language, like 'int' for representing integers, 'float' for decimals, and 'if' for decision-making.

Operators in 'C'

Symbols that perform operations on values, such as '+' for addition, '-' for subtraction, '*' for multiplication, and '/' for division.

Preprocessor Directives

Commands that tell the compiler to perform specific tasks before compiling code, like #include to bring in external code and #define to replace values.

Control Structures

Statements that control the flow of execution in a program, including decision making structures like 'if', 'else', and 'switch', and loop structures like 'while', 'do-while', and 'for'.
