WebWe must initialize it to point to the desired variable. This is achieved by assigning the address of that variable to the pointer variable, as shown below. int a = 10; int *pa; pa = … WebIn this case, newvar2 will be a pointer (and something must be too). auto *newvar1 = myvector, newvar2 = something; Here, newvar2 is the pointee type, eg. std::vector, and the initializer must be adequate. In general, if the initializer is not a braced initializer list, the compiler processes auto like this:

Then, you can use malloc in your main (after your first scanf):. temp = malloc(d * sizeof(int)); In C arrays and pointers are closely related.
