Re: String Swap Not Working

just like to add a point here,When we use
strcpy() function it actuaylly copies the 2nd string to the 1st one.

but when we assign
*p=x;
x=*q
*q=*p
like this here we only interchange the address variable.

these two things gives the same output but internal operation is different.

I think there's only one reason why your code will never work as you expected: you declare read-only strings. Although you didn't declare it with the const keyword, declaring string that way makes your string variable untouchable.

Its possible that what the original thread starter meant by 'swap' was to actually interchange the pointers to the read-only strings as Dave and Dream2Code have suggested.
