Array Errors Quiz

What is the error in the following array initialization? int arr[3] = {1, 2, 3, 4};

• The correct initialization should be int arr[4] = {1, 2, 3, 4};

• The array size should be 4 instead of 3

• The elements should be separated by spaces

• The array should be initialized with square braces

int arr[5];

arr[5] = 10;

• arr[-1] = 10;

• arr[4] = 10;

• arr[4] = {10};

• arr = 10;

Find the error in passing the array to the function: void printArray(int arr);

• The error is that the array is not passed by pointer.

• The error is that the array is not passed by address.

• The error is that the array is not passed by value.

• The error is that the array is not passed by reference. The function signature should be void printArray(int *arr) or void printArray(int arr[])

Identify the error in multidimensional array declaration: int arr[][] = {{1, 2}, {3, 4, 5}};

• int arr[][] = {{1, 2}, {3, 4, 5}}; should be corrected to int arr[][] = {{1, 2}, {3, 4, 5}, {6, 7}};

• int arr[][] = {{1, 2}, {3, 4, 5}}; should be corrected to int arr[][] = {{1, 2}, {3, 4, 5, 6}};

• int arr[][] = {{1, 2}, {3, 4, 5}}; should be corrected to int arr[][] = {{1, 2}, {3, 4, 5}, {6}}

• int arr[][] = {{1, 2}, {3, 4, 5}}; should be corrected to int arr[][] = {{1, 2}, {3, 4}};

Find the error in passing the array to the function: void printArray(int arr[5]);

• Add the size to the function signature: void printArray(int arr[], int size);

• Pass the array as a pointer to the first element: void printArray(int *arr);

• Change the function signature to int printArray(int arr[5]);

• Add a reference symbol to the function signature: void printArray(int &arr);

Identify the error in multidimensional array declaration: int arr[][] = {{1, 2}, {3, 4}, {5}};

• int arr[][] = {{1, 2}, {3, 4}, {5, 6, 7}};

• int arr[][] = {{1, 2}, {3, 4}, {5, 6};

• int arr[][] = {{1, 2}, {3, 4}, {5, 6, 7, 8}};

• int arr[][] = {{1, 2}, {3, 4}, {5}}; should be int arr[][] = {{1, 2}, {3, 4}, {5, 6}};

What is the error in the following array initialization? int arr[2] = {1, 2, 3};

• The correct initialization should be int arr[2] = {1, 2};

• The correct initialization should be int arr[3] = {1, 2, 3};

• The array should be initialized with a loop instead of direct assignment

• The array size should be larger to accommodate all elements

What is the incorrect array size error in the code snippet? int arr[2] = {1,2,3,4,5};

• Array size should be increased to accommodate more elements or the number of elements initialized should be reduced.

• The array size should be kept the same and the elements should be initialized with default values

• Array size should be decreased to limit the number of elements

• The array size should be increased without changing the number of elements initialized

Find the error in passing the array to the function: void printArray(int *arr);

• The array should be passed by value instead of by pointer

• The array should be declared as a global variable instead of passing it to a function

• To pass an array to a function in C, the size of the array should also be passed along with the array pointer. For example, the function signature should be void printArray(int *arr, int size) where 'size' indicates the number of elements in the array.

• The function should return the array instead of printing it

Identify the error in multidimensional array declaration: int arr[][] = {1, 2};

• int arr[] = {{1, 2},{3, 4}, {5, 6}};

• int arr[][] = new int[][]{{1, 2}, {3, 4}, {5, 6}};

• int arr[][] = new int[3][2]{{1, 2}, {3, 4}, {5, 6}};

• The correct declaration should be int arr[][] = {{1, 2}, {3, 4}, {5, 6}};
