What will be the value of the i variable when the while e loop finishes its execution?
The initial value of 'i' is 0. The while loop condition checks if 'i' is not equal to 0, but since 'i' is initially 0, the condition fails immediately. Therefore, the code inside the while loop is not executed. Instead, the control goes to the else block, where 'i' is incremented by 1 (i = i + 1). As a result, the final value of 'i' when the loop finishes its execution is 1.
And operator able to perform bitwise shifts is coded as (Choose two.)
The bitwise shift operators are '<<' for left shift and '>>' for right shift. The '<<' operator shifts the bits of a number to the left, effectively multiplying the number by 2 for each shift position. The '>>' operator shifts the bits to the right, effectively dividing the number by 2 for each shift position. Both '++' and '--' are not bitwise operators; they are unary operators used for incrementing and decrementing values, respectively.
What will the value of the i variable be when the following loop finishes its execution?
In the given loop, 'range(10)' generates a sequence of numbers from 0 to 9. The variable 'i' iterates over these values. When the loop completes, the last value assigned to 'i' is 9. Thus, the value of the 'i' variable when the loop finishes its execution is 9.
The following expression -
is:
The expression 1 + (-2) is equivalent to 1 - 2, which results in -1.
A compiler is a program designed to (Choose two.)
A compiler is a program designed to check the source code in order to see if it's correct and to translate the source code into machine code. Checking the source code for correctness involves syntax and semantic analysis, ensuring the code adheres to language rules and logical frameworks. Translating the source code into machine code is the primary function of a compiler, converting high-level language instructions into a form that can be executed by a computer's CPU.
