752 Working with Strings

int main()

{

string s1 (“Take”);

string s2 (“Took”);

cout<<“\n s1=”<<s1;

cout<<“\n s2=”<<s2;

cout<<“\n After swap()”;

s1.swap(s2);

cout<<“\n s1=”<<s1;

cout<<“\n s2=”<<s2;

return 0;

}

OUTPUT

s1= Take

s2= Took

After swap()

s1= Took

s2= Take

Explanation: In the above program, string objects s1 and s2 are declared and initialized with

“Take” and “Took”, respectively. The swap() function exchanges the contents of s1 and

s2; that is, the contents of s1 are assigned to s2 and vice versa. The output of the program is as

given above.
