QString qstr("hello,word"); constchar* p = qstr.toLocal8Bit().data(); 方法二: constchar*p = qstr.toStdString().data(); //转换过来的是常量 方法三: QString str="abc"; char*ch; QByteArray ba = str.toLatin1() ch = ba.data(); 三、更有效的构造 String 我们通常通过"+"连接多个...
(trolltech) Answer:In order to convert a QString to a char*, then you first need to get a latin1 representation of the string by calling toLatin1() on it which will return a QByteArray. Then call d处理字符串的一些js/jq方法(去除HTML,去除空格,计算真实长度,截取中英文字符) 去除html标签...

QByteArray ba=aaa.toLatin1();const char *c_str = ba.data();PS:c_str所指向的内存单元,如果你想长时间使用你应该复制出来,要不可能过数行代码后,你再读你的数据,c_str所指向的内存单元就不是你以前读的内容了。函数返回的指针临时变量,不能长时间使用!!! 具体代理...
88. Merge Sorted Array(从后向前复制) Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note:You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements...
QString converts the const char * data into Unicode using the fromAscii() function.2)QChar[]数组初始化 Cpp代码 1. static const QChar data[4] = { 0x0055, 0x006e, 0x10e3, 0x03a3 };2. QString str(data, 4);也可以这样 Cpp代码 1. QRegExp pattern;2. static const QChar unicode[]...
