Common editing<\/strong><\/p>\n

  • Intend your code. Usually use 4 whitespaces.<\/li>\n
  • Never use tabs to intend, only spaces!<\/li>\n
  • Structure the code in logical blocks. Use one newline between the blocks.<\/li>\n
  • Use brackets! Use { }! Use ()! Its much more safer and readable! Use {} after every for if while! Don't be lazy. Use auto completion if you are lazy. One exception for this rule: for throwing exceptions. e.g. if(false) throw \"Shit\"\n

    C and C++ mixing<\/strong><\/p>\n

  • Never mix C and C++<\/li>\n
  • Don't use the old C include files with prefix \".h\" e.g. math.h Instead use cmath<\/li>\n
  • Always write the full standard namespace when using standard functions e.g. std::abs<\/li>\n
  • Write \"using namespace myspace\" only for non-standard namespaces.<\/li>\n
  • Never write \"using namespace\" in header files. Only in cpp files.<\/li>\n

    Loops<\/strong><\/p>\n

  • The first running variable in a loop is \"i\", then \"j\" and \"k\".
    \nNever use something like \"ii\", \"iii\". Don't use \"l\" (lower L) eiher, it looks too much like \"i\"<\/li>\n
  • Prefer for() loops for while() loops. They have a clearer syntax how log the loop is running. And you prevent endloss loops.<\/li>\n
  • Every while() loop can be written as for() loop()<\/li>\n

    common function calls<\/strong><\/p>\n

  • Pass non derived POD object as value. Like int float char<\/li>\n
  • Pass non-POD objects as const reference. This performs no deep-copy and the caller can be sure that his object is not modified.<\/li>\n
  • Pass by pointer only if you must modify the object! The caller knows throw the pointer notation that the object may be altered<\/li>\n
  • Pass functions objects by value???<\/li>\n

    get functions<\/strong><\/p>\n

  • Functions which returns a variable and not change the object<\/strong> must be marked with \"const<\/strong>\"<\/li>\n","protected":false},"excerpt":{"rendered":"
