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...

C++ Programming: From Problem Analysis to Program Design
- Answer in C++ only Reverse Polish Notation (RPN) is a mathematical notation where every operator follows all of its operands. For instance, to add three and four, one would write "3 4 +" rather than "3 + 4". If there are multiple operations, the operator is given immediately after its second operand; so the expression written "3 - 4+ 5" would be written "3 4 - 5 +" first subtract 4 from 3, then add 5 to that. Transform the algebraic expression with brackets into RPN form. You can assume that for the test cases below only single letters will be used, brackets [] will not be used and each expression has only one RPN form (no expressions like a*b*c) Input 1 (a+(b*c)) Output abc*+arrow_forwardC++arrow_forward.arrow_forward
- C++ please solve the equationnnnnnarrow_forwardcan obtain the remainder of this division by using the % operator. For example, 10 % 3 is 1. In C++, the % can be applied only to integer operands; it cannot be applied to floating-point types. The following program demonstrates the modulus operator:arrow_forwardPlease write with simple codes.arrow_forward
