Your team will write a function that reverses a C-string, to practice using pointers. You must use pointers and C-strings for th
Nutka1998 [239]

Answer:

Here is the C++ program:

#include <iostream> //to use input output functions

#include<string.h> // to manipulate strings

using namespace std; //to identify objects like cin cout

void ReverseString(char* original_str){ // function that reverses a C-string

       char* ptr1 = original_str;  // pointer that points to the start of C-string

       char* ptr2 = original_str; // pointer that points to the start of C-string initially

       for (int i = 0; i < strlen(original_str)- 1; i++) {//iterates through the length of the C-string

           ptr2++;} //moves ptr2 to the end of the C-string

       while(ptr1 < ptr2) {// swaps each character of C-string using pointers

               char temp = *ptr1; //declares a temp variable to hold character that *ptr1 points to

               *ptr1 = *ptr2;

               *ptr2 = temp;

               ptr1++; //increments ptr1 moving it forward

               ptr2--;   }} //decrements ptr2 moving it backwards

int main(){ //start of main() function

       char input_str[]="";  /// declare a C-string

       cout<<"Enter original string: "; //prompts user to enter a string

       cin>>input_str; // reads that C-string from user

       ReverseString(input_str); //calls function to revserse the input string

       cout<<"\nReversed string: "<<input_str;} // displays the reversed string

Explanation:

The program has a function ReverseString that takes a C-style string as parameter and reverses the string using pointers.

The ptr1 and ptr2 are pointers that initially point to the beginning of original string.

for (int i = 0; i < strlen(original_str)- 1; i++) this statement has a for loop that iterates through the original string and moves the ptr2 to point at the end or last character of the C-string. strlen() method is used to get the length of the C-string. At each iteration ptr2 moves one time forward until the last character of the C-string is reached.

while(ptr1 < ptr2) statement has a while loop that works as follows:

checks if ptr1 is less than ptr2. This evaluate to true because the index of first character that ptr1 points to is 0 and last character is 5 so 0<5. Hence the statements inside while loop execute which swaps the character of C-string from beginning and end index using ptr1 and ptr2. a temp variable is declated to hold character that *ptr1 points to.

For example

original_string = "xyz" Then temp = *ptr1; stores the character that *ptr1 points to i.e. 'x'

*ptr1 = *ptr2; This statement assigns the character that *ptr2 points to the *ptr1. Basically these pointers are used as indices to the C-string. So this means that the *ptr1 now stores the last character of the C-string that is pointed to by *ptr2. So *ptr1 = 'z'

*ptr2 = temp; This statement assigns the character that temp stores to the *ptr2. We know that temp contains the first character i.e 'x'. So *ptr2 = 'x'      

ptr1++; The ptr1 is incremented to 1. This means it moves one position ahead and now points to the second character of the C-string.

ptr2--; The ptr2 is decremented to 1. This means it moves one position backwards and now points to the second character of the C-string.

Now the while loop breaks because ptr1 < ptr2 condition evaluates to false.

So the original string is reversed using pointers. Hence the output is:

Assume that the population of Mexico is 114 million and that the population increases 1.01 percent annually. Assume that the pop
AfilCa [17]

Answer:

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

// variables

   double mexico = 114;

   double usa = 312;

   double mexicoRate = .0101;

   double usaRate = .0015;

// calculate population after every year until mexico population exceed the usa populationn

   while (usa>mexico)

   {

// print the population

       cout<<"Mexico's population ::"<<mexico<<" million."<<endl;

       cout<<"USA's population ::"<<usa<<" million."<<endl;

// update the population

       mexico+=mexico*mexicoRate;

       usa-=usa*usaRate;

   }

return 0;

}

Explanation:

Declare and initialize mexico and usa with their initial population.Also declare and initial their increase and decrease rate.Find the population of both the  country each year until mexico population exceeds the usa population.

Output:

Mexico's population ::114 million.                                                                                          

USA's population ::312 million.                                                                                            

Mexico's population ::115.151 million.                                                                                      

USA's population ::311.532 million.

Mexico's population ::270.546million.                                                                                      

USA's population ::274.213 million.                                                                                        

Mexico's population ::273.278million.                                                                                      

USA's population ::273.802 million.
