C++ provides the functionality to find an element in the given range of elements in a vector. This is done by the find() function which basically returns an iterator to the first element in the range of vector elements [first, last) on comparing the elements equals to the val (value to ...
void vector_Find_ex1() { vector<string> vsExt = {"OPJ", "TXT"}; if ( -1 == vsExt.Find("SPC") ) // if not found, returns -1 { out_str("No find!"); } int ii = vsExt.Find("xT", 0, false, false);// if found will return the index out_int("ii = ", ii); } ...
QVector<int> data = {1, 3, 2, 8, 5, 7};std::vector<int> stdData = data.toStdVector();auto maxElementIter = std::max_element(stdData.begin(), stdData.end()); 同样,我们可以说 “I am converting the QVector to a standard vector using the toStdVector method before applying the...

1,vector传入find()的是元素,而不用指明该vector。 2,array传入find()的是元素,而不用指明该array。 这两个问题的解法会包含最初问题的通用解法。 vector或者array有两个属性:一是首元素地址,二是大小。因此有两种方法设计接口: 1, template<typename elemType> ...
若要删除std::vector中的element,正规的方式该用find() generic algorithm,若find()找到了,会传回该iterator,若找不到,将传回vector.end()。这种写法远比用for loop干净很多。 1 /* 2 (C) OOMusou 2006http://oomusou.cnblogs.com 3 4 Filename : VectorFindAndErase.cpp ...
To find a signal changepoint,findchangeptsemploys a parametric global method. The function: Chooses a point and divides the signal into two sections. Computes an empirical estimate of the desired statistical property for each section. At each point within a section, measures how much the property...
