Punctuation marks

• Brackets {}:
  • Open bracket on the same line as the statement.
  • Closing bracket under the last line.
• Parentheses ():
  • No space between parenthesis and the code inside
  • In a statement, space before ( and after )
  • In class or function, space after ) only

Example:

int GetLargerNumber(int num_one, int num_two) {
    if (num_one > num_two) {
        return num_one;
    }
    else {
        return num_two;
    }
}

Formatting

Spacing

• Types, variable, operators and literal value, separated by one horizontal space.

string message = "hello world";

• Classes, functions, global variables declaration and preprocessor directives, separated by one vertical space.

#include <iostream>    // preprocessor directive
 
float pi = 3.1415;    // global variable
 
class MyClass {        // class
  public:
    myClass() {
  }
};
 
int main() {        // function
  return 0;
}

Indentation

Each new block (loop, method…) opening should be intended.

Level of indentation: ?? (2 or 4)

Line length

• 80 characters
