Sorting an array of Strings in C++

By: Ignatius in C++ Tutorials on 2012年03月16日 [フレーム]

This simple C++ program sorts the elements of an integer array and prints them.

#include <iostream>
using namespace std;
#include <cstring>
int main()
{
 // declare two arrays named tname with 1-Dimension
 // and name with 2-Dimension
 char tname[20], name[20][20];
 // normal variables...
 int i, j, n;
 cout<<"Enter the number of names: ";
 cin>>n;
 // outer loop for counter...
 for(i=0; i<n; i++)
 {
 cout<<"\nEnter the name(one word) "<<(i+1)<<": ";
 cin>>name[i];
 }
 // inner for loop, read row by row set outer for loop...
 for(i=0; i<n-1; i++)
 // innermost for loop, read column by column of the characters...
 for(j = i+1; j<n; j++)
 // set the condition...
 // strcmp - compare the string standard library function
 // do the sorting...
 if(strcmp(name[i], name[j])>0)
 {
 // strcpy - copy the strings...
 // compare and swap...
 strcpy(tname, name[i]);
 strcpy(name[i], name[j]);
 strcpy(name[j], tname);
 }
 cout<<"\nSorted names:\n";
 for (i =0; i<n; i++)
 cout<<"\n"<<name[i];
 cout<<endl;
 return 0;
}
