Pointers Use CasesPointers Use Cases

When you pass a variable to a function, you're essentially passing its value. This means the function receives a copy of the data. Any modifications made inside the function DO NOT affect the original variable.

cpp

main.cpp

We can use pointers to enable a function to alter the original variable. This involves passing a memory address as an argument instead of the actual value.

cpp

main.cpp

Note

You can bypass the creation of a pointer to a variable and instead directly use the address-of operator when passing a variable.

Tarefa

  • Create a function that swaps values of two variables.
  • Call this function.
  • Output the values of variables after the swap.
