36 Questions
What does an array consist of?
Ordered set of similar data items
How are the elements of an array stored in memory?
In consecutive memory locations
When must an array be declared?
Before it is used
What does the size specified during array declaration inform the compiler to do?
Allocate and reserve memory locations
In an array, what is the range of indices?
0 to (n-1)
What is the syntax for declaring an array with 'n' elements?
data_type array_name[n];
What happens if the number of values to be initialized is more than the size of the array in C language?
Compilation error occurs
In C, how are the memory locations initialized when a partial array initialization is done?
All elements are set to zero automatically
Which of the following will result in an automatic size determination of the array in C?
int d[5]={10};
When an array is initialized with a string in C, why is the array size larger than the string length?
Due to an extra null character added at the end of the string
What error occurs if an attempt is made to initialize an array using 'char b="COMPUTER"' in C?
'COMPUTER' exceeds maximum string length
In C, what happens if no array size is specified during initialization?
Array grows dynamically depending on initial values
Which statement accurately describes runtime initialization for arrays in C?
'scanf' is used to read user input and initialize arrays
What is the outcome of initializing an integer array in C with more values than its specified size?
'Excess elements are ignored' without warnings
How does C handle an array initialization where fewer values are provided than its size?
'Remaining elements automatically set to zero'
What effect does adding a partial initialization have on the remaining uninitialized array elements in C?
Remain uninitialized without a default value
What happens when the number of values to be initialized is less than the size of the array in C language?
The elements are initialized to zero automatically.
When initializing an array in C with a string, why is the array size larger than the string length?
Strings are null-terminated, so an extra byte is allocated for the null character.
In C, what occurs when an attempt is made to initialize an array using char b='COMPUTER'?
Compilation error due to incorrect single quotes usage.
What effect does runtime initialization have on array elements in C?
Array elements are filled with user-entered values at execution time.
How does C handle an array initialization with fewer values provided than its specified size?
Initializes the given values and sets the rest to zero by default.
What error occurs with the declaration int a={9,2,4,5,6}; in C?
Too many initial values provided for the array size.
Which statement regarding partial array initialization in C is correct?
'Partial array initialization initializes specific elements, leaving others untouched.
'Initialization without size' in C refers to which scenario?
'Declaring an array without specifying its number of elements.'
'Initialization with all zeros' in C involves which process?
'Setting all elements of the array to zero automatically.'
In C, what determines the size of an array when initialized with fewer values than its capacity?
The number of elements explicitly mentioned during declaration.
What is the syntax to declare an array in C with 5 elements of type float?
float array[5];
If an array 'numbers' in C has been declared as 'int numbers[10];', what is the range of indices for this array?
0 to 9
During initialization, what happens if more values are provided than the size specified for an array in C?
Values are truncated to fit the array size
What does the statement 'int data[3] = {10, 20};' do in C?
Initializes the array to {10, 20, 0}
If an array 'marks' is declared as 'float marks[5];' in C, what values will be stored in the array before initialization?
Garbage values
What could be the consequence of initializing an array in C without specifying its size?
'Declaration syntax error' at compile time
If an array 'characters' is declared as 'char characters[4];' in C, how many characters can it hold at maximum considering a null terminator at the end?
3 characters
'int values[8];' is declared in C. What will be the state of all elements of 'values' before explicit initialization?
'Random values' for all elements
What does 'int scores[] = {95, 88, 75};' represent when initializing an array in C?
'Scores' declared without size but with values assigned
'float values[6];' is declared in C. How many bytes will be allocated to hold all elements of this array?
'24 bytes'
Learn about arrays, how they are defined as ordered sets of data items, stored in consecutive memory locations, and accessible using the same name. Understand why arrays must be declared before use, specifying their size during declaration.
