Incrementing Pointers, Exact Sequence

Question

I have just started to learn C, and I get that

*a = *b;
a++;
b++;

and

*a++ = *b++

are equivalent, but i

Answer 1

1)

*a = *b;
a++;
b++;

is equivalent to

*a = *b;
a = a+1;
b = b+1

2)

x = *a++

is equivalent to

x = *a;
a = a+1;

and

*b++ = x

is equivalent to

*b = x;
b = b+1;

so

*a++ = *b++

is equivalent to

*a = *b;
a = a+1;
b = b+1

3)

*(++a) = *(++b)

is equivalent to

a = a+1;
b = b+1
*a = *b;
