Explanation of Solution
The program errors and the corrections are explained in the in-lined comments:
#include <iostream>
using namespace std;
int main()
{
//speed is a int pointer which is declared and
//memory allocated
int *speed = new int; //Line 1
//double pointers are declared
double *travelTime; //Line 2
double *distance; //Line 3
//value of 65 is stored in the memory allocated
//pointed to by speed using address of operator
//& which is wrong
///&speed = 65; //Line 4
//correct line is
*speed = 65;
//value is attempted to be stored at a memory location
//which is pointed to by travelTime but actually
//no memory has yet been allocated so memory

The rates vary depending on whether the useR is residential (R), commercial( C) , or industrial (I). Any other code should be treated as an error. The program should accept the subscriber ID, Subscriber Name, his total electrical consumption in a month, and the code of the consumer type. The rates are computed as follows: R: 50 plus .50 per kwh used C: 100 for the first 1000 kwh and 0.45 for each additional kwh I: 180 for the first 1000 kwh and 0.75 for each additional kwharrow_forward

You have been asked to write a program to assign seats on each train of the railway havingonly (capacity: 100 seats). Your program should check whether it is a valid seat number or not.Also print its berth type i.e lower berth, middle berth, upper berth, side lower berth, side upperberth. Furthermore, then print a ticket indicating the person's seat number and whether it’s in the firstclass or economy section of the train. Use a single-subscripted array to represent the seating chartof the train. Initialize all the elements of the array to 0 to indicate that all seats are empty. As eachseat is assigned, set the corresponding element of the array to 1 to indicate that the seat is no longeravailable.arrow_forward
