Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Pointers point — they don't hold the value.
A pointer is a variable whose value is the memory address of another variable. It lets you access that variable indirectly.
↳ Pointer = address holder; * reads/writes the value at that address.
Star declares, ampersand assigns.
↳ Use `type *name = &variable;` to declare and point in one line.
Change x without touching x.
Writing `*p = 20` changes the value at the address p holds — which is x itself.
↳ Dereferencing on the left side of `=` writes to the original variable.
Pointers are variables that store the memory address of another variable. They are a core feature of C that enables direct memory access, efficient array handling, dynamic memory, and function-level data sharing. This ki...
~18 min · full explanation, examples & memory tricks in the app
21 questions laddered from warm-up to topper-level, each with an explanation. A taste:
Which statement best describes what a pointer stores?
BeginnerA memory address
A pointer is a variable whose value is a memory address, not a data value.
Which operator returns the address of a variable?
Beginner`&`
The `&` operator is the address-of operator; `*` is the dereference operator.
If `p = &x`, which expression is equal to `x`?
Beginner`*p`
`&` and `*` are inverses: if `p = &x`, then `*p` is the same as `x`.
What does `int *p;` declare?
Beginner`p` is a pointer to an `int`
Read `int *p` as 'p is a pointer to int'.
