What if you want to accumulate all elements in a container?
The accumulate of STL allows us to write loops by ourselves:
# Include # Include # Include # Include # Include Int main (){Std: vector Vect. push_back (1 );Vect. push_back (2 );Vect. push_back (3 );Vect. push_back (4 );Std: cout Std: accumulate (vect. begin (), vect. end (), 0, std: plus }
Output:
Accumulate, copy, vector: push_back (STL sample)The sample code below uses strates how to use the accumulate, copy, and vector: push_back STL functions in Visual C ++.Required header: Prototype:Template _ Type accumulate (inputiterator first, inputiterator last, _ type init)
