You are to write two functions, printString() and testString(), which are called from the main function.
Some sample runs are given below:
Note:
Hints:
prob1.cpp
#include <iostream>
#include <string>
using std::string;
using std::cout;
using std::endl;
bool checkAnswer(const string &nameOfTest, bool received, bool
expected);
// Implement printString here
// Implement testString here
// EDIT CODE BELOW ONLY FOR TESTING (ANY CODE BELOW WILL BE
OVER-WRITTEN DURING GRADING WITH DIFFERENT TESTS)
int main() {
cout << "Test if the string contains two consecutive
characters that are the same" << endl;
{
string s = "hello";
cout << "Contents of array : ";
printString(s);
checkAnswer(s, testString(s), true);
}
{
string s = "world";

// system("pause"); // comment/uncomment if needed
return 0;

bool expected) {

You are to write two functions, printString() and testString(), which are called from the main function....
In C++: You are to write two functions, printString() and testString(), which are called from the main function. printString (string) prints every character in the string to std::cout with a space after every character and a newline at the end. testString (string) returns true if the string contains characters that are in sorted order, false otherwise. You may assume that all characters are lowercase and only alphabetical characters are present. See the main() to see how the two functions are...
Add a recursive Boolean function called checkRecurse to class IntegerLinkedList to check if any two consecutive integers in the linked list are equal (return true in this case, false otherwise). You may assume that the list is not empty. A recursion “helper” function is already included in class IntegerLinkedList. You only need to write the recursive function. For example, checkRecurseHelper() should return true for the linked list shown below. A main function (prob3.cpp) is given to you to add data...

You are given a Q1.h file with overloaded function prototypes for isOrdered. Implement this overloaded function into a file named Q1.cpp. Q1.cpp should only include your function implementation, the necessary #include directives if needed, and should not contain anything else such as the main function or global variable declarations. Test your code using a separate main.cpp file where you implement a sufficient number of test cases. You should use Q1.h as a header file and Q1main.cpp as a main function...
You are to implement a MyString class which is our own limited implementation of the std::string Header file and test (main) file are given in below, code for mystring.cpp. Here is header file mystring.h /* MyString class */ #ifndef MyString_H #define MyString_H #include <iostream> using namespace std; class MyString { private: char* str; int len; public: MyString(); MyString(const char* s); MyString(MyString& s); ~MyString(); friend ostream& operator <<(ostream& os, MyString& s); // Prints string MyString& operator=(MyString& s); //Copy assignment MyString& operator+(MyString&...
You are given a partial implementation of two classes. GroceryItem is a class that holds the information for each grocery item. GroceryInventory is a class that holds an internal listing of GroceryItems as well as the tax rate for the store. Your inventory could be 100 items it could be 9000 items. You won’t know until your program gets the shipment at runtime. For this you should use the vector class from the C++ standard library. I've completed the GroceryItem.h...
Call each of the print functions in the main() using string double-pointers in the main void print(string ** s){ **s = "Hello"; cout<< **s <<endl; } void print(string *x){ *x = "World"; cout<<*x<<endl; }
Using C++ Use the below program. Fill in the code for the 2 functions. The expected output should be: The:fox:jumps:over:the:fence.: The:fox:jumps:over:the:fence.: The:fox:jumps:over:the:fence.: The:fox:jumps:over:the:fence.: #include #include #include using namespace std; //Assume a line is less than 256 //Prints the characters in the string str1 from beginIndex //and inclusing endIndex void printSubString( const char* str1 , int beginIndex, int endIndex ) { } void printWordsInAString( const char* str1 ) { } int main() { char str1[] = "The fox jumps over the...
C++ / Visual Studio Implement the member function below that returns true if the given value is in the container, and false if not. Your code should use iterators so it works with any type of container and data. template< typename Value, class Container > bool member( const Value& val, const Container& cont ); just implement this function in the code below #include <iostream> #include <array> #include <deque> #include <list> #include <set> #include <string> #include <vector> using namespace std; #define...
