Kompilasi atau kompile (compile) adalah ….
- A.
Proses membuat source code
- B.
Proses merubah source code ke bahasa C
- C.

- E.
Proses merubah source code ke bahasa C sehingga dapat diedit setiap saat oleh user
Correct Answer
D. Proses merubah source code ke bahasa mesin sehingga bisa dieksekusi atau dijalankanExplanation
The correct answer is "proses merubah source code ke bahasa mesin sehingga bisa dieksekusi atau dijalankan." This is because the process of compiling involves translating the source code written in a high-level programming language into machine code, which can be executed by the computer. This transformation allows the program to be run and perform its intended tasks.Rate this question:

Bagian dari program yang akan diabaikanoleh compiler adalah….
- A.
Variabel
- B.
Tipe data
- C.
Konstanta
- D.
Identifiers
- E.
Komentar
Correct Answer
E. KomentarExplanation
Komentar adalah bagian dari program yang tidak akan diproses oleh compiler. Komentar digunakan untuk memberikan penjelasan atau catatan dalam kode program, namun tidak akan mempengaruhi eksekusi program. Compiler akan mengabaikan komentar saat melakukan kompilasi dan menghasilkan output program yang akhir.Rate this question:

- B.
30
- C.
31
- D.
32
- E.
33
Correct Answer
D. 32Explanation
The correct answer is 32 because the question is asking for the number of keywords in the C programming language. C has a total of 32 keywords, including "if," "else," "for," "while," and "return," among others. These keywords have predefined meanings and cannot be used as variable names or identifiers in the program.Rate this question:

Penulisan #include <iostream.h> pada source code bahasa C, berfungsi untuk ….
- A.
Merupakan komentar dan tidak berpengaruh pada program
- B.
Memberitahukan preprocessor kompiler untuk menyertakan header file standard iostream
- C.
Merupakan titik awal dimana seluruh program C++ akan mulai dieksekusi
- D.
Merupakan standard output stream dalam C++ (biasanya monitor)
- E.
Merupakan cara yang paling sering digunakan untuk mengakhiri program
Correct Answer
B. Memberitahukan preprocessor kompiler untuk menyertakan header file standard iostreamExplanation
The correct answer is "memberitahukan preprocessor kompiler untuk menyertakan header file standard iostream". This is because the #include directive is used in C++ to include the header file "iostream", which provides input and output stream objects such as cin and cout. The preprocessor will replace the #include directive with the contents of the specified header file before compiling the program.Rate this question:

Suatu nilai yang tidak dapat diubah selama proses program berlangsung adalah ….
- A.
Konstanta
- B.
Variabel
- C.
Deklarasi
- D.
Tipe data
- E.
Operator
Correct Answer
A. KonstantaExplanation
A value that cannot be changed during the execution of a program is called a constant. Unlike variables, which can be assigned new values, constants remain the same throughout the program. This allows programmers to define fixed values that are used repeatedly in their code, providing clarity and maintainability.Rate this question:

- E.
Penugasan (Assignment operator)
Correct Answer
C. Suatu pengenal (identifier) yang digunakan untuk mewakili suatu nilai tertentu di dalam proses programExplanation
The correct answer is "suatu pengenal (identifier) yang digunakan untuk mewakili suatu nilai tertentu di dalam proses program". In the C programming language, a variable is used to represent a specific value within the program. It acts as an identifier that can be assigned a value and manipulated throughout the program's execution. Variables can hold different types of data, such as integers, characters, or floating-point numbers, and their values can be changed during the program's execution.Rate this question:

Output yang dihasilkan untuk operasi 9%5 dalam bahasa C adalah ….
- A.
0
- B.
1
- C.
2
- D.
3
- E.
4
Correct Answer
E. 4Explanation
The output of the operation 9%5 in the C language is 4. The % operator in C is the modulus operator, which returns the remainder of the division between two numbers. In this case, when 9 is divided by 5, the remainder is 4.Rate this question:

Outputyang dihasilkan dari operasi a = 5 + 7 % 2 adalah ….
- A.
5
- B.
6
- C.
7
- D.
8
- E.
9
Correct Answer
B. 6Explanation
The output of the operation a = 5 + 7 % 2 is 6. This is because the % operator represents the modulo operation, which calculates the remainder of the division. In this case, 7 divided by 2 equals 3 with a remainder of 1. Therefore, the expression becomes 5 + 1, resulting in a value of 6 for the variable a.Rate this question:

- A.
Float
- B.
Void
- C.
Char
- D.
Int
- E.
Double
Correct Answer
A. FloatExplanation
The correct answer is float because the given range (-3.4E-38 s/d 3.4E+38) corresponds to the range of values that can be stored in a float data type. Float is a data type used to represent decimal numbers with single precision, meaning it can store values with a smaller range and less precision compared to double data type.Rate this question:

- C.
Pergantian baris secara otomatis
- D.
Karakter yang dimasukkan tidak akan ditampilkan
- E.
Karakter yang dimasukkan terlihat pada layar
Correct Answer
D. Karakter yang dimasukkan tidak akan ditampilkanExplanation
The explanation for the given correct answer is that the getchar() function is used to read a single character from the input stream, but it does not display the character on the screen. It only reads the character and stores it in a variable for further use in the program. The other options mentioned in the question are all related to the functionality of the getchar() function, except for this one.Rate this question:

Correct Answer
A. Pernyataan untuk menyatakan keadaan awal dari variabel controlExplanation
The "inisialisasi" in the given code is intended to state the initial condition or value of the control variable. This is important because it sets the starting point for the loop and determines how many times the loop will be executed. By initializing the control variable, the loop can begin executing from a specific point and follow the desired pattern or sequence.Rate this question:
