In [3], c(G) is defined. In this paper we will assume that,
G is a nilpotent group of class 2 and cd(G)={1,m}, where
m=|G:Z(G|1/2. Then we will calculate the nonlinear
irreducible characters of G, when G′=Z(G) and we will show
that c(G)=|G:Z(G)|1/2c(Z(G)). Also when G′ < Z(G) and G has
a unique minimal normal subgroup, that is, G is a p-group, we
will show that c(G)=|G:Z(G)|1/2c(Z(G)).
