Select the incorrect statement 1 - data type describes what type of values are going to be stored
2 - data usage describes whether the data item is used as a variable or constant
3 - data scope states the access permission
4 Data type describes where the values are going to be stored​

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
