Understanding Function Return Statements and Parameters in Structured Programming with C

This guide explores function return statements, local variables, and parameter types in C programming. It highlights the difference between formal parameters (declared in function headers) and actual parameters (used in function calls). You will learn how they must match in type, order, and number, although their names need not coincide. The text includes practical examples of function calls and sample programs illustrating these concepts, ensuring a comprehensive understanding of how to effectively implement functions in C programming.

  3. Note Formal and Actual Parameters Formal parameters are variables that are declared in the header of the function definition. Actual parameters are the expressions in the calling statement. Formal and actual parameters must match exactly in type, order, and number. Their names, however, do not need to match. Computer Science: A Structured Programming Approach Using C
