#### Abstract

In this paper, variational iteration method is applied for ﬁnding the solution of differential equations with piecewise constant arguments. A correction functional is constructed by a general Lagrange multiplier, which can be identiﬁed by variational theory. This technique provides a sequence of functions which converges to the exact solution of the problem without discretization of the variables. The ﬂexibility and adaptation provided by the method have been verified by an example.
