Pointer
- *ptr_var= var ptr_var= &var wheIF you are using a pointer in a function, make it appear on the variable used in it when you give the pointer the address of a variable, whatever the value of the variable, the *ptr_var is that value.
Function: used to find the address of the variable? to save memory space and achieve faster execution time.
What happens to a value within a function: When you put an address of a cell of RAM into a function, you enable the function of modifying the value of a specific cell. Meanwhile, if you put the value, it is like giving another cell, a copy but not the specific cell.
