Course Introduction
Programs for practice
To sort strings in alphabetical order in C++ programming, you have to ask to the user to enter the two string, now start comparing the strings, if found then make a t variable of same type, and place the first string to the t, then place second string to the first, then place t to the second string using the function strcpy(), and continue until last as shown in the following program.
Source Code: Print Hello World
/* C++ Program - Sort String in Alphabetical Order */
#include<iostream.h>
#include<conio.h>
#include<string.h>
void main()
{
clrscr();
char str[5][20], t[20];
int i, j;
cout<<"Enter any five string (name) : ";
for(i=0; i<5; i++)
{
cin>>str[i];
}
for(i=1; i<5; i++)
{
for(j=1; j<5; j++)
{
if(strcmp(str[j-1], str[j])>0)
{
strcpy(t, str[j-1]);
strcpy(str[j-1], str[j]);
strcpy(str[j], t);
}
}
}
cout<<"Strings (Names) in alphabetical order : \n";
for(i=0; i<5; i++)
{
cout<<str[i]<<"\n";
}
getch();
}
Output
Enter any five string (name) :
lmn
abc
bgh
hjn
acd
Strings (Names) in alphabetical order :
abc
acd
bgh
hjn
lmn
