* Q1. When moving though an array we use the size to move through byte by byte but when we pass two values or a value we are able to do 'value++'. Why in example 1 we use size and in example 2 we use '++', when both are .
Example 1.
 n = sum(a, 11, sizeof(int), isEven, &e); // Where a is an array
 int sum(void* x, int n, int size, bool (*f)(void*, void*), void* result)
 {...
 ptrcharx = ptrcharx + size;
 ...}
Example 2.
 b = exchange(&x, &y, sizeof(int), (int(*)(void *, void *))ig); // x =4, y =3
 int exchange(void *a, void *b, int n, int(*f)(void *, void*))
 {...
 a1 = (char*)a;
 a1++;
 ...
 }
