// Blocks are statements of code, just like a function, that are able to be used as data.
// Below is a simple block with an integer argument that returns the argument plus 4.
int (^addUp)(int n); // Declare a variable to store the block.
^(int n) {
return n + 4;
}
int (^addUp)(int n); // Declare a variable to store a block.
void (^noParameterBlockVar)(void); // Example variable declaration of block with no arguments.
// Blocks have access to variables in the same scope. But the variables are readonly and the
// value passed to the block is the value of the variable when the block is created.
