The value of X is 7. Some computer languages (or notations) interpret X+1 as 8 and others interpret it as Y. Why?
What will be an ideal response?
In everyday life (i.e., natural language), we do not distinguish between the name of a variable, its address, and its value. When we say, X = X + 1, we mean that the value we have given the variable X is incremented by 1 to become 8. X is the name of the variable whose value is 7.
If we regard X as the representation of the character X, then X is 0x58 (the ASCII code for X). Adding 1 to X gives us 0x59 which is the ASCII code for Y.
Some computer languages allow you to operate on the name of a variable. This question demonstrates that it is important to appreciate the difference between name, address, and value.
