Q: Before execution compiler converts high-level program into machine language program, the machine language program is called

A. Source program
B. Object program
C. exe program
D. None of this

Correct Option: B
Remarks:

Explanation:

Answer: Object program

A source program is a text file that contains instructions written in a high level language. It can not be executed (made to run) by a processor without some additional steps. A source program is also called a source file, source code, or sometimes, just source.

A source program is a collection of instructions written using a programming language, while an object program is an output generated after compiling the source program.

An EXE file contains an executable program for Windows. EXE is short for "executable," and it is the standard file extension used by Windows programs. For many Windows users, EXE files are synonymous with Windows programs, making ".exe" one of the most recognizable file extensions.

Q: Which of the following symbol is used to denote a pre-processor statement?

A. !
B. #
C. ~
D. ;

Correct Option: B
Remarks:

Explanation: #

Q: What is the output of the following C code?


#include <stdio.h>

int main() {
    int x = 5;
    printf("%d", x++);
    return 0;
}

A. 5
B. 6
C. 4
D. The code will result in a compile error

Correct Option: A
Remarks:

Explanation:

Answer: A

Explanation: The value of x is first printed using printf, and then incremented by the ++ operator. Therefore, the output will be 5.

Q: Which of the following is not a valid data type in C?

A. char
B. int
C. float
D. string

Correct Option: D
Remarks:

Explanation:

Answer: D

Explanation: string is not a valid data type in C. Instead, strings are represented as arrays of characters in C.

Q: What is the output of the following C code?


#include <stdio.h>

int main() {
    int x = 5;
    if (x > 10) {
        printf("x is greater than 10");
    }
    else {
        printf("x is less than or equal to 10");
    }
    return 0;
}

A. x is greater than 10
B. x is less than or equal to 10
C. The code will result in a runtime error
D. The code will result in a compile error

Correct Option: B
Remarks:

Explanation:

Answer: B

Explanation: The if statement checks if x is greater than 10, which it is not. Therefore, the code inside the else block is executed, resulting in the output "x is less than or equal to 10".

Q: What is the output of the following C code?


#include <stdio.h>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    printf("%d", *(arr + 2));
    return 0;
}

A. 1
B. 2
C. 3
D. 4

Correct Option: C
Remarks:

Explanation:

Answer: C

Explanation: The expression *(arr + 2) is equivalent to arr[2], which accesses the third element of the arr array. Therefore, the output will be 3.

Q: Who is the creator of the C programming language?

A. James Gosling
B. Dennis Ritchie
C. Bjarne Stroustrup
D. Ken Thompson

Correct Option: B
Remarks:

Explanation:

Dennis Ritchie created the C programming language while working at Bell Labs in the 1970s.

The C programming language was created by Dennis Ritchie. Dennis Ritchie was an American computer scientist born on September 9, 1941, in Bronxville, New York. Along with Ken Thompson, Ritchie developed the C programming language at Bell Labs (AT&T's Bell Telephone Laboratories) in the early 1970s.

The development of C was closely tied to the creation of the Unix operating system, which also originated at Bell Labs. C was designed to provide a high-level programming language that allowed for efficient system programming, making it well-suited for developing the Unix operating system.

Dennis Ritchie's work on C and Unix had a profound impact on the field of computer science. The C programming language became widely adopted and influenced the development of many subsequent programming languages. Additionally, Unix became a highly influential operating system, with its design principles influencing the development of other operating systems.

Dennis Ritchie passed away on October 12, 2011, but his contributions to computer science and programming continue to be celebrated, and his legacy lives on through the widespread use of the C programming language.
