用于对任何数据类型的变量进行排序的程序

编写一个程序，用于在不使用std :: sort的情况下对任何数据类型的变量进行排序。

例子：

Input :  2000, 456, -10, 0
Output : -10   0   456   2000    

Input :  "We do nothing"
         "Hi I have something"
         "Hello Join something!"
         "(Why to do work)"
Output :(Why to do work)   
         Hello Join something!
         Hi I have something
         We do nothing   

上面的示例显示，我们可以将任何数据类型元素作为输入存在，并且输出将以输入数据的排序形式出现。
解决此问题的想法是制作一个模板。

方法1(编写我们自己的排序)在下面的代码中，我们实现了Bubble Sort对数组进行排序。

// CPP program to sort array of any data types.
#include 
using namespace std;
  
// Template formed so that sorting of any 
// type variable is possible
template 
void sortArray(T a[], int n)
{   
    // boolean variable to check that 
    // whether it is sorted or not
    bool b = true;
    while (b) {
        b = false;
        for (size_t i=0; i a[i + 1]) {
                T temp = a[i];
                a[i] = a[i + 1];
                a[i + 1] = temp;
                b = true;
            }
        }
    }
}
  
// Template formed so that sorting of any 
// type variable is possible
template 
void printArray(T a[], int n)
{
    for (size_t i = 0; i < n; ++i) 
        cout << a[i] << "   ";    
    cout << endl;
}
  
// Driver code
int main()
{
    int n = 4;
    int intArr[n] = { 2000, 456, -10, 0 };
    sortArray(intArr, n);
    printArray(intArr, n);
  
    string strArr[n] = { "We do nothing",
                         "Hi I have something",
                         "Hello Join something!",
                        "(Why to do work)" };
    sortArray(strArr, n);
    printArray(strArr, n);
  
    float floatArr[n] = { 23.4, 11.4, -9.7, 11.17 };
    sortArray(floatArr, n);
    printArray(floatArr, n);
  
    return 0;
}

输出：

-10   0   456   2000   
(Why to do work)   Hello Join something!   Hi I have something   We do nothing   
-9.7   11.17   11.4   23.4

方法2(使用库函数)
我们可以在C++中使用std :: sort对任何数据类型的数组进行排序。

// CPP program to sort array of any data types.
#include 
using namespace std;
  
// Template formed so that sorting of any 
// type variable is possible
template 
void printArray(T a[], int n)
{
    for (size_t i = 0; i < n; ++i) 
        cout << a[i] << "   ";    
    cout << endl;
}
  
// Driver code
int main()
{
    int n = 4;
    int intArr[n] = { 2000, 456, -10, 0 };
    sort(intArr, intArr + n);
    printArray(intArr, n);
  
    string strArr[n] = { "We do nothing",
                         "Hi I have something",
                         "Hello Join something!",
                        "(Why to do work)" };
    sort(strArr, strArr + n);
    printArray(strArr, n);
  
    float floatArr[n] = { 23.4, 11.4, -9.7, 11.17 };
    sort(floatArr, floatArr+n);
    printArray(floatArr, n);
  
    return 0;
}

输出：

-10   0   456   2000   
(Why to do work)   Hello Join something!   Hi I have something   We do nothing   
-9.7   11.17   11.4   23.4
