this is to swap to strings....but in output the whole strings are swapped leaving first as it is...why it is so #include<iostream.h> int main() { char a[]="ajeet"; char b[]="singh"; long x=*a; long y=*b; cout<<x<<":"<<y; x=x+y; y=x-y; x=x-y; *a=x; *b=y; cout<<x<<":"<<y; cout<<&a<<endl; cout<<&b<<endl; }
