Declaring and Initializing Pointers in C

• int *p; // p contains address of an int
• float *x // x contains address of a float
• p = &quantity // quantity is an int variable
• p = &f where f is float is an erroneous statement, because *p results in a wrong ans
• int x, *p = &x; // initializes p to address of x
• int *p=&x, x is invalid
