Explanation of Solution
The program execution is explained in the in-lined comments:
#include <iostream>
using namespace std;
int main()
{
//declare variables dec1, dec2 and initialize
double dec1 = 2.5;
double dec2 = 3.8;
//declare double pointers p and q
double *p, *q;
//assign the address of variable dec1 to p
p = &dec1;
//assign the value of dec2 - dec1 to the memory
//location pointed to by p which is dec1
//so dec1 now holds the value (3.8-2.5 =) 1.3
*p = dec2 - dec1;
//q is assigned the value of p so both the pointers
//now point to variable dec1
q = p;
//content of the memory location pointed to by q
//is assigned 10.00 so dec1 holds the value 10.0
*q = 10.0;
//the contents of the memory location pointed to by p
//i.e dec1 is assigned the value of the RHS expression
//RHS = 2 &*#x00A0;10 + 10...
