Q2. How will you print the address of a variable without using a pointer?
Ans. 
You can print the address of a variable without using a pointer by using the & operator in C/C++.
• Use the & operator before the variable name to get its address, e.g. int num = 10; printf("Address of num: %p", &num);

• You can also pass the variable directly to a function that expects a pointer, e.g. void printAddress(int *ptr) { printf("Address: %p", ptr); } int num = 20; printAddress(&num);
