Selection Sort in C++

[dadafak]

Selection Sort in C++. By this method, you can easily sort a for loop code and array. Below are the sample codes:

1. #include<iostream>
   
2. #include<conio.h>
   
3. using namespace std;
   
4. int
   
   main(
   
   )
   
5. {
   
6. int
   
   arraylength,
   
   num[
   
   1000
   
   ]
   
   ,
   
   num1,
   
   d,
   
   num2=
   
   0
   
   ;
   
7. cout<<
   
   "Enter the total no. of element: "
   
   ;
   
8. cin>>
   
   arraylength;
   
9. 
   
10. for
    
    (
    
    int
    
    i=
    
    0
    
    ;
    
    i<
    
    arraylength;
    
    i++
    
    )
    
11. {
    
    cout<<
    
    "Enter No."
    
    <<
    
    i+
    
    1
