6
Q
Unsigned to two-complement equation
A
7
Q
Range for T2U operation
A
TMin ≤ x ≤ Tmax
8
Q
Range for U2T
A

9
Q
What happens when an operation in C is performed where one operand is signed and the other is unsigned
A
C implicitly casts the signed argument to unsigned and performs the operations assuming the numbers are nonnegative
10
Q
Implicit casting
A
When an expression of one type is assigned to a variable of another
11
Q
Explicit casting
A
Using the type between brackets
tx = (int) ux;
12
Q
What is truncating
A
Reducing the number of bits representing a number
13
Q
Rule for truncation of two-complement number
A
The most significant bit is converted to a sign bit
