Using void pointer to an array

Question

I was just trying to use a void pointer to an integer array ,I tried to see if i can print the array back by casting it back into int. But it is giving me some random value.

Answer 1

you should not add numbers to void pointers. cast it before. (x = *((int *)arr+j);)

When you add number to a pointer, the compiler multiply this number with the size of the type that is pointed, so if you add number to a pointer to wrong type, you will get wrong result.

if I remember correct, add to void* is illegal, but some compilers adds the exact number in bytes (like it is char*). `
