C++ sorting program: Operation of this C++ example source code is used to open a text file, read the content and sort in a particular order. These kinds of file operations related programs are very important for academics. It is easy to follow and there is the simple code. This object oriented C++ programming will do the following functions while compiling the code.

• Open a Text format file,
• Display text file’s content,
• Content sorting,
• Display sorted content.
• Read: Call by reference programs

All above operations are happening based on the C++ sorting functionality. This C++ source code can be used as a LAB exercises program or exam program. All students can use this important program for free of cost. Feel free to share about us to the world.

Write a C++ code for text file content sorting with the use of strcpy() method.

// Header files section
#include<iostream.h>
#include<string.h>
#include<conio.h>
#include<fstream.h>
void main()
{
clrscr(); // Removes the previous output screen
char k[30],s[35][30],x[30];  //Variables declaration
int v,C1;
v=C1=0;
ifstream ifs("C:\\karthikh-venkat.txt");
ofstream sort("C:\\SORTED-TEXT.txt");
cout<<"\n\t Contents Before Sorting Operation";
while(!ifs.eof())
{
ifs.getline(k,30); // Reading Text file
strcpy(s[C1],k);
cout<<k<<"\n";
if(C1)
{
// Sorting operations takes place
strcpy(s[C1],k);
for(v=0;v<=C1;v++)
{
if(strcmp(s[C1],s[v])<0)
{
strcpy(x,s[v]);
strcpy(s[v],s[C1]);
strcpy(s[C1],x);
}
}
}
C1++;
}
cout<<"\n Display After Sorting";
for(v=0;v<C1;v++)
{
sort<<s[v];
cout<<"\n"<<s[v]; // Final output display
}
getch();
}
