Solution
The function declaration is needed in C both during function definition and declaration. This is because the function declaration gives the compiler information about the function name, return type, and parameters. The function definition provides the actual body of the function. If a function is used before it is defined, a declaration is necessary. Without this, the compiler wouldn't know about the function's existence.
