for(int i = 0 ; i < (1 << 7)

; i++) {

This code snippet is a for loop that initializes a variable i to 0 and iterates until i is less than 2 raised to the power of 7 (128).

The expression (1 << 7) is a bitwise left shift operation that moves the binary digit 1 seven places to the left, resulting in the binary value 10000000. This value is equivalent to 2 to the power of 7, which is 128.

The loop will execute 128 times, with the value of i incrementing by 1 on each iteration.
