"WebJan 24, 2024 · The resultant type is the type of the left operand. The result of an assignment expression is always an l-value. These operators have right-to-left associativity. The left operand must be a modifiable l-value. In ANSI C, the result of an assignment expression isn't an l-value. That means the legal C++ expression (a += b) += c isn't allowed in C ...

WebIn the first loop, we are using the bitwise left shift operator (<<) to calculate the powers of 2. The left shift operator is equivalent to multiplying by 2. So, for example, 1 << 3 is the same as 1 * 2 * 2 * 2, which gives us 8. In the second loop, we are simply printing out the values in the array using cout. The output should look like this: WebFeb 11, 2024 · The left-shift operator causes the bits in shift-expression to be shifted to the left by the number of positions specified by additive-expression. The bit positions that have been vacated by the shift operation are zero-filled. A left shift is a logical shift (the bits that are shifted off the end are discarded, including the sign bit).
