Swap Two String using Third variable

Write a C++ Program to Swap Two String using Third variable. Here’s simple C++ Program to Swap Two String using Third variable in C++ Programming Language.

C++ Strings : 

String is a sequence of characters. char data type is used to represent one single character in C++. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.

C++ provides following two types of string representations:

  • The C-style character string.
  • The string class type introduced with Standard C++.

The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

Here is source code of the C++ Program to Swap Two String using Third variable. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


/* C++ Program to Swap Two String using Third variable  */

using namespace std;

int main()
  int i=0, j=0, k=0;
  char str1[20], str2[20], temp[20];

  cout<<"\nEnter the First String :: ";

  cout<<"\nEnter the Second String :: ";

  cout<<"\nStrings before swapping are ::\n";
  cout<<"\n\tString 1 = "<<str1<<"\n";
  cout<<"\n\tString 2 = "<<str2<<"\n";
  i=0, j=0;
  i=0, j=0;
  cout<<"\nStrings after swapping :: \n";
  cout<<"\n\tString 1 = "<<str1<<"\n";
  cout<<"\n\tString 2 = "<<str2<<"\n";

  return 0;


/* C++ Program to Swap Two String using Third variable  */

Enter the First String :: Codez

Enter the Second String :: Club

Strings before swapping are ::

        String 1 = Codez

        String 2 = Club

Strings after swapping ::

        String 1 = Club

        String 2 = Codez

Process returned 0

Above is the source code for C++ Program to Swap Two String using Third variable which is successfully compiled and run on Windows System.The Output of the program is shown above .
