Алиаскар Куватов ok, #include <stdio.h> int main() { int a[10] = {1,2,3,4,5,6,7,8,9,0}; int* p = a; int t = *(p+9); *(p+9) = *(p+1); *(p+1) = t; printf("%d\n%d", a[9], a[1]); return 0; } // you can use any loop to get input, but idea that i used can be applied here https://code.sololearn.com/c08l2TC7g7zb/?ref=app

do you mean something like this? #include <stdio.h> int main() { int a[10] = {1,2,3,4,5,6,7,8,9,0}; int* p = a; *(p+9) = *(p+1); printf("%d", a[9]); return 0; } // it’s a C file, didn’t notice the tag was C++. But should be the same. https://code.sololearn.com/c08l2TC7g7zb/?ref=app

Enter the array data, and swap the second and last element of the array.

I can’t fix it for you. I showed almost everything. You can use a while/for to get input. Rest should be the same.
