Ques 1 Datatype
Which is the following is not primitive datatype ?
a) int
b) float
c) Array
d) char
An array, on the other hand, is not a primitive data type. It's a composite data structure that stores a collection of elements of the same data type. Each element in an array has a specific index or position, allowing you to access and manipulate individual elements within the collection. Arrays provide a way to organize and manage multiple related values under a single name.
Ques 2 Datatype
What is the range of the char ?
a) -128 to 127
b) -127 to 128
c) -128 to 0
d) -127 to 128
A char data type typically stores signed integers and covers the range from -128 to 127. This holds true across most programming languages. It uses 1 byte of memory, and half of that goes to representing the sign. If you need non-negative values, use unsigned char (ranging from 0 to 255). While some systems might use 2 bytes for char, the standard representation and common range is -128 to 127.
Ques 3 Datatype
What is the range of the char ?
a) 2 byte
b) 4 byte
c) 1 byte
d) None of these
The size of a char data type can vary depending on the system and compiler, but it is typically 1 byte. This allows it to represent integer values from -128 to 127. However, some systems might use 2 bytes for char, extending the range to -32768 to 32767. If you need to store unsigned characters (non-negative values), you can use the unsigned char type, which typically has a range of 0 to 255.
Ques 4 Datatype
Which of the following is not a data type in C?
a) string
b) int
c) float
d) double
Ques 5 Datatype
What is the range of values that can be stored by an int data type in C?
a) -2147483648 to 2147483647
b) -32768 to 32767
c) -9223372036854775808 to 9223372036854775807
d) -1.7976931348623157e+308 to 1.7976931348623157e+308
Ques 6 Datatype
What is the range of values that can be stored by a float data type in C?
a) -32768 to 32767
b) -2147483648 to 2147483647
c) -9223372036854775808 to 9223372036854775807
d) -3.4028234663852886e+38 to 3.4028234663852886e+38
