Understanding Pointers and Variable Outputs in C Programming

This exercise focuses on pointer manipulation and variable outputs in C programming. It examines how to properly declare integer variables and pointer variables, set their values, and print relevant memory addresses and values. By analyzing given code snippets, learners will determine the output produced by specific variable and pointer configurations, enhancing their understanding of how pointers reference memory addresses in C.

  2. Ex1: What is the output of the following code ? firstvalue is 10 secondvalue is 20

  3. Ex2: What is the output of the following code ? firstvalue is 10 secondvalue is 20

  4. Ex7: introduce int variables x and y and int* pointer variables p and q. Set x to 2, y to 8, p to the address of x, and q to the address of y. Then print the following information: • The address of x and the value of x. • The value of p and the value of *p. • The address of y and the value of y. • The value of q and the value of *q. • The address of p (not its contents!). • The address of q (not its contents!).
