In the code given below m not getting ,
1) wht he has written in "Console.WriteLine("Enter Value p[{0}]:", i);" wht is P[{0}] n wht is i ,,,,,

2)
Console.WriteLine("c[{0}]={1}, c[{2}]={3}", i, c, j, c[j]);
wht is c[{0}] = {1},c[{2}]={3} " , i , c

In Console.WriteLine, {0} acts as a placholder for a value to be put in a string.
So Console.WriteLine("Enter Value p[{0}]:", i); (Let i in the for loop be 3) would print out: Enter Value p[ 3 ]:

I would prefer to change this to
Console.WriteLine("Enter Value Number {0} :", i);
which in the same case( i = 3 ) would print out: Enter Value Number 3 :
