C Programming

• 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.

Input and Common Errors

• 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.
