#include <stdio.h> int main() { int a, b; scanf("%d%d", &a, &b); if (a == b) { printf("%d\n", Equal); } else if (a >> b) { printf("%d\n", Above); } else if (a << b) { printf("%d\n", Less); } return 0;
This code reads two integers and tries to compare them, but it uses bitwise shift operators (`>>` and `<<`) instead of comparison operators. The `Equal` and other identifiers are also not defined as variables or constants.

- The conditions `a >> b` and `a << b` perform bitwise shifts, not comparisons. You likely intended to use relational operators like `>` or `<` to compare the values of `a` and `b`.
- The names `Equal`, `Above`, and `Less` are used in `printf` but are not defined anywhere. You need to either define them as variables with values, or print the strings directly using quotes.
