MyClass::MyClass(const QColor &color;)    : color(color){}

空白

// Wrongif(foo){} // Correctif (foo) {}

char *x;const QString &myString;const char * const y = "hello";

// Wrongchar* blockOfMemory = (char* ) malloc(data.size()); // Correctchar *blockOfMemory = reinterpret_cast<char *>(malloc(data.size()));

//Wrongx      = rect.x();y      = rect.y();width  = rect.width();height = rect.height();

大括号

// Wrongif (codec){} // Correctif (codec) {}

class Moo{};

// Wrongif (address.isEmpty()) {    return false;} // Correctif (address.isEmpty())    return false;if (x) {    // do something strange    yyyyyyyyy = yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy +                zzzzzzzzzzzzzzzzzzzzzz;}

// Correctif (address.isEmpty()  !isValid()       !codec) {    return false;}

// Wrongif (address.isEmpty())    return false;else {    qDebug("%s", qPrintable(address));    ++it;} // Correctif (address.isEmpty()) {    return false;} else {    qDebug("%s", qPrintable(address));    ++it;}// Wrongif (a)    if (b)        ...    else        ... // Correctif (a) {    if (b)        ...    else        ...}

// Wrongwhile (a); // Correctwhile (a) {}

圆括号

// Wrongif (a && b  c) // Correctif ((a && b)  c) // Wronga + b & c // Correct(a + b) & c

switch语句

switch (myEnum) {case Value1:    doSomething();    break;case Value2:    doSomethingElse();    // fall throughdefault:    defaultHandling();    break;}

断行

// Correctif (longExpression    + otherLongExpression    + otherOtherLongExpression) {}

//Wrongif (dsfljfsfskjldsjkljklsjdk    && fdsljsjdsdljklsjsjkdfs    && dsfljkdfjkldksdfjdjkfdksfdkjld) {    sadjdjddadhsad;}//Correctif (dsfljfsfskjldsjkljklsjdk        && fdsljsjdsdljklsjsjkdfs        && dsfljkdfjkldksdfjdjkfdksfdkjld) {    sadjdjddadhsad;}

对 whle 或else if，不存在这个问题：

void MyClass::setColor(const QColor &c){    color = c;}

注意：在构造函数中，会遇到同样的问题。但无论你信与不信，下面的可以工作

while (dsfljfsfskjldsjkljklsjdk       && fdsljsjdsdljklsjsjkdfs       && dsfljkdfjkldksdfjdjkfdksfdkjld) {    sadjdjddadhsad;}
