是否有一个标准的函数返回值的数组?
Is there a standard function that returns the position(not value) of the max element of an array of values?
例如:
说,我有一个这样的数组:
say i have an array like this:
sampleArray = [1,5,2,9,4,6,3]
sampleArray = [1, 5, 2, 9, 4, 6, 3]
我想要一个函数,返回3个整数,它告诉我,sampleArray [3]是数组中的最大值。
I want a function that returns the integer of 3 that tells me that sampleArray[3] is the largest value in the array.
在STL, 的std :: max_element
提供了迭代器(可用于获取与指数的 的std ::距离
,如果你真的想要的话)。
In the STL, std::max_element
provides the iterator (which can be used to get index with std::distance
, if you really want it).
int main(int argc, char** argv) {
int A[4] = {0, 2, 3, 1};
const int N = sizeof(A) / sizeof(int);
cout << "Index of max element: "
<< distance(A, max_element(A, A + N))
<< endl;
return 0;
}
