Q: Which of the following is not a valid declaration in C?
1. short int x;

2. signed short x;

3. short x;

4. unsigned short x;

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

Correct Option: D
Remarks:

Explanation:

All are valid

Q: What is the output of this C code?


#include <stdio.h>
int main()
 {
  float f1 = 0.1;
  if (f1 == 0.1f)
  printf("equal\n");
  else
  printf("not equal\n");
 }

A. not equal
B. equal
C. Output depends on compiler
D. None of the mentioned

Correct Option: B
Remarks:

Explanation:

Output

equal

0.1f results in 0.1 to be stored in floating point representations.

Q: Which is correct with respect to the size of the datatypes?

A. char > int > float
B. int > char > float
C. char < int < double
D. double > char > int

Correct Option: C
Remarks:

Explanation:

char has lesser bytes than int and int has lesser bytes than double in any system

Option C is correct with respect to the size of the datatypes in the C programming language. The char data type typically has a size of 1 byte, the int data type typically has a size of 4 bytes, and the double data type typically has a size of 8 bytes. Therefore, char < int < double in terms of size. However, it's worth noting that the size of these data types can vary depending on the specific implementation and architecture of the system being used.

In C language, data types can be arranged based on their size in bytes. Here's a common arrangement from smallest to largest:

char: Typically 1 byte.
short: Usually 2 bytes.
int: Generally 4 bytes.
float: Usually 4 bytes.
long: Typically 4 bytes on 32-bit systems and 8 bytes on 64-bit systems.
double: Usually 8 bytes.
long long: Typically 8 bytes.
long double: Can vary, often 10 or 16 bytes.

Please note that the actual size of these data types might vary depending on the compiler and system architecture.

Q: Which of the datatypes have size that is variable?

A. Array
B. Structure
C. Union
D. All

Correct Option: D
Remarks:

Explanation:

Since the size of the structure depends on its fields, it has a variable size.

Q: Which one is a modifier in data type?

A. sign
B. unsign
C. long
D. All

Correct Option: D
Remarks:

Explanation:

All are modifier in data type.

Q: What is short int in C programming?

A. short is the qualifier and int is the basic datatype
B. All are Qualifier
C. Basic data type of C
D. All of the mentioned.

Correct Option: A
