Do not stop when a program first produces the expected output; also check readability, maintainability, efficiency, and robustness.
Store computed results in variables before displaying them. Program state matters more than transient console output.
Analyze control flow and data flow, then verify your reasoning with a debugger or temporary diagnostic output.
When requesting help, explain what you tried, what you understand, and the precise point that remains unclear.

Whitespace in a scanf format usually consumes any amount of input whitespace. Character input needs extra care because it may read a pending newline.
Match each format specifier to its destination type, and include & when an address is required.
Use ASCII punctuation in source code and end statements with an ASCII semicolon.
Declare and initialize variables before reading their values.
Integer division produces an integer result, even if that result is later assigned to a floating-point variable.
When Microsoft Visual C warns about functions such as scanf, understand the safer alternatives first. Legacy exercises may require _CRT_SECURE_NO_WARNINGS.
