Coding Standards for C programming

 This document contains some of the coding standards that the students have to follow , when they
are writing the programs.

Indent style :

• Indent the entire body of each function to one level of indentation.
• Use three spaces or tab per level of indent.
• Select the size of the indentation you prefer and uniformly apply that throughout the program.

                       

• If there are several levels of indentation, each level should be intended the same additional amount of space.
• Indent the statement/s in the body of an if statement
• If a statement is split across two or more lines, indent all subsequent lines.

                       

• Indent the statement/s in the body of an while/for statements.

                       

Comments:

• Describe the purpose of each function in the program using a comment
• Add a comment to the right brace } of every function, to indicate the end of function.
• Add comments to describe the purpose of the statements in the program

      Example:

                         

Statements:

• Separate the definitions and executable statements in a function with one blank line.

                           

• Place a blank line before and after every if statement.

                         

White spaces:

• Place a space after each comma(,) in printf and scanf statements.

                         

                          

• Place space on either side of a operator

                         

• Unary operators should be placed directly next to their operands with no intervening spaces.

                           

Naming conventions:

• Choose meaningful variable name.

                           

• When there are multiple words in a variable, begin each after the with a capital letter camel case (eg: totalCommissions)

Programming practices:

• Try to avoid using more than three levels of nesting in loops.
