far, and huge pointers. In older Intel processors, the registers were 16-bit while the address bus was 20-bit wide. This mismatch meant registers couldn’t hold complete addresses. To manage this, memory was split into 64 kB segments. Concepts like near, far, and huge pointers in C were...
Discover the various levels of pointers in C and C++. Learn how many levels you can use and their significance in programming.
We assigned the variable a to the ptr *int using the operator &a here&a will fetch the address of the variable and assigned it to the pptr. In the next step, assign the variable b to the ptr *int using the operator &b, here&b will fetch the b variable’s address and assign it...
