Will my program compile, link, and run if I have the prototype but not the function body? Will it compile, link, and run if I have the function body but not the prototype? Prototype and call, but no function body? Call, function body, but no prototype?

What will be an ideal response?

If I have the prototype but not the function body, (no call) the code compiles, links and runs. Function body, no prototype, no call, it compiles, links, and runs. Prototype and call, but no function, code compiles but doesn’t link. Call, function body but no prototype doesn’t compile (unless the function body is “before” the call, such as above the main function.
