List of available C programming examples with output :

Compile, Run C program in GCC Linux

Tips to write good programming code

  1. Analyse the problem: many programmer start witting before analysing the problem, this is very bad habit, ignore this always analyse the problem by collecting information from concerned person.
  2. Make algorithm or flow chart: before writing code, make flow chart or algorithm of your logic and code through that.
  3. Documentations: insert proper comments with function name, description, date and time, arguments details. Everything related to code must be there; it will help you or others to understand your code.
  4. Indentations: Code that you had written must be in proper indentation, so that you can read or debug your code easily. Close all braces at the same indent as open. Always insert a tab when you write code within the block.
  5. Define Macros: Always define macros for values, do not use values within the code, macros are easily editable and you can edit values whenever required without changing in the functions.
  6. Initialize all data: Don’t do only declarations, try to assign initial values to them. For examples if you are declaring a variable to store age of the student. Declare with initialization like int age=0;
  7. Use enumeration: Define enum for numerical literals instead of direct literal.
  8. Make functions: always divide your code into small pieces (called function), it will help you to reduce duplicate and you can edit or debug code easily.
  9. Don’t ignore warnings: Some programmers ignored warnings while compiling or running the programs. It is not good for program health a program must have 0 Error and 0 Warning.
  10. Test your program with different inputs: to test program is logically correct or not, test it with different inputs and analyse the output.
