Link Between Pointer and Variable

When you modify the value through the dereferenced pointer, you are essentially modifying the content of the memory location it points to. This directly affects the original variable.

Remember

Changing the value through *(p_variable) is equivalent to changing the value of variable.

Opgave

  1. Declare and initialize the pointer with a variable address.
  2. Change the value of dereferenced pointer to zero.
  3. Output the variable value.
