Question

C++

Define a generic function called CheckOrder() that checks if four items are in ascending, neither, or descending order. The function should return -1 if the items are in ascending order, 0 if the items are unordered, and 1 if the items are in descending order.

The program reads four items from input and outputs if the items are ordered. The items can be different types, including integers, strings, characters, or doubles.

Ex. If the input is:

bat hat mat sat
63.2 96.5 100.1 123.5

the output is:

Order: -1
Order: -1

#include <string>
#include <iostream>

using namespace std;

// TODO: Define a generic method called CheckOrder() that
// takes in four variables of generic type as arguments.
// The return type of the method is integer

// Check the order of the input: return -1 for ascending,
// 0 for neither, 1 for descending

int main(int argc, char* argv[]) {
// Read in four strings
string stringArg1, stringArg2, stringArg3, stringArg4;
cin >> stringArg1;
cin >> stringArg2;
cin >> stringArg3;
cin >> stringArg4;
// Check order of four strings
cout << "Order: " << CheckOrder(stringArg1, stringArg2, stringArg3, stringArg4) << endl;

// Read in four doubles
double doubleArg1, doubleArg2, doubleArg3, doubleArg4;
cin >> doubleArg1;
cin >> doubleArg2;
cin >> doubleArg3;
cin >> doubleArg4;
// Check order of four doubles
cout << "Order: " << CheckOrder(doubleArg1, doubleArg2, doubleArg3, doubleArg4) << endl;

return 0;
}

Given below is the code for the question. There will be no prompt, just provide input as in screenshot. Please do rate the answer if it helped. Thank you.

#include <string>
#include <iostream>

using namespace std;

// TODO: Define a generic method called CheckOrder() that
// takes in four variables of generic type as arguments.
// The return type of the method is integer

// Check the order of the input: return -1 for ascending,
// 0 for neither, 1 for descending
template <typename T>
int CheckOrder(T arg1, T arg2, T arg3, T arg4){
  
   if(arg1 >= arg2 && arg2 >= arg3 && arg3 >= arg4) //descending
       return 1;
   else if(arg1 <= arg2 && arg2 <= arg3 && arg3 <= arg4) //ascending
       return -1;
   else
       return 0;
}

int main(int argc, char* argv[]) {
// Read in four strings
string stringArg1, stringArg2, stringArg3, stringArg4;
cin >> stringArg1;
cin >> stringArg2;
cin >> stringArg3;
cin >> stringArg4;
// Check order of four strings
cout << "Order: " << CheckOrder(stringArg1, stringArg2, stringArg3, stringArg4) << endl;

// Read in four doubles
double doubleArg1, doubleArg2, doubleArg3, doubleArg4;
cin >> doubleArg1;
cin >> doubleArg2;
cin >> doubleArg3;
cin >> doubleArg4;
// Check order of four doubles
cout << "Order: " << CheckOrder(doubleArg1, doubleArg2, doubleArg3, doubleArg4) << endl;

return 0;
}
