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
