One GB is 210 MB.

One GB is not 220 MB. Hence, the given statement is “False”.

One GB is 210 MB and not 220 MB. One GB equals 1024 MB and 1024 is equal to 210 hence one GB equals 210 MB.

The ASCII data set consists of 128 characters numbered 0 through 127. In the ASCII data set, the position of the first character is 0, the position of the second character is 1, and so on.

In ASCII, A is the not the 65th character. Hence, the given statement is “False”.

A is encoded as the binary number 1000001 and it is the 66th character in the ASCII character code. However, its position is 65 because the position of the first character is 0.

The number system that we use in our daily life is called the decimal system, or base 10. Computers represent everything as a sequence of 0s and 1s, that is, binary numbers, hence the number system that a computer uses is called binary, or base 2.

The number system used by a computer is base 2. Hence, the given statement is “True”.

Computers represent everything as a sequence of 0s and 1s, that is, binary numbers, hence the number system that a computer uses is called binary, or base 2.

An assembler is a program that translates a program written in assembly language into an equivalent program in machine language.

An assembler translates the assembly language instructions into machine language. Hence, the given statement is “True”.

Writing instructions in assembly language is easier that writing in machine language. A computer cannot execute assembly language instructions directly hence the instructions first need to be translated into machine language. A program called an assembler translates the assembly language instructions into machine language.

The compiler checks the source program for syntax errors and translates the program into the equivalent machine language, provided not syntax errors exist. The equivalent machine language program is called an object program.

A compiler translates the source program into an object program. Hence, the given statement is “True”.

A text editor is used to create a program following the rules, or syntax, of the high-level language and it is called the source code, or source program. The compiler checks the source program for syntax errors and translates the program into the equivalent machine language, provided not syntax errors exist. The equivalent machine language program is called an object program.

A computer can understand only machine language, in order to run this program successfully, the code must first be translated into machine language. There are many steps involved in doing so. One of the steps in case of C++ program is processing of preprocessor directives.

In a C++ program, statements that begin with the symbol # are called preprocessor directives. Hence, the given statement is “True”.

A C++ program typically contains the statement #include <iostream>. In a C++ program, statements that begin with the symbol # are called preprocessor directives. These statements are processed by a program called preprocessor.

A computer can understand only machine language, in order to run this program successfully, the code must first be translated into machine language. There are many steps involved in doing so. One of the steps in case of C++ program is translation of the source program into equivalent machine language which is known as the compilation process. A compiler is used for the compilation process.

All logical errors, such as division by 0, are not reported by the compiler. Hence, the given statement is “False”.

The compiler only checks for syntax errors such as missing brackets, out of scope function calls, etc. It does not guarantee that the program will run correctly. During execution, the program might terminate abnormally due to logical errors, such as division by zero. Such errors are not checked by the compiler.

Object Oriented Design (OOD) gets started with the identification of components called objects and their mutual interactions required to accomplish a functionality.

In object-oriented design (OOD), a program is a collection of interacting objects. Hence, the given statement is “True”.

In OOD, the first step in the problem-solving process is to identify the components called objects, which form the basis of the solution, and then to determine how these objects interact with one another. For example, in a program that automates the shopping cart process for a local store the two main objects are the shopping cart and the customer.

Object Oriented Design (OOD) gets started with the identification of components called objects and their mutual interactions required to accomplish a functionality.

An object consists of data and operations on that data. Hence, the given statement is “True”.

In OOD, the first step in the problem-solving process is to identify the components called objects, which form the basis of the solution. This is followed by the specification of the data for each object and the possible operations to be performed on that data. For example for a shopping cart the data would include item description, item price, item quantity and the operations would include checking the total value of the shopping cart, the presence or absence of an item in the cart, etc.

In the early 1990s a joint committee of the American National Standards Institute (ANSI) and International Organization for Standardization (ISO) was established to standardize the syntax of C++. In mid-1998, ANSI/ISO C11 language standards were approved. Most of today’s compilers comply with these new standards.

ISO stands for International Organization for Standardization. Hence, the given statement is “True”.

ISO stands for International Organization for Standardization and it played a big role in the standardisation of the syntax of C++ programming language.
