Consider following;int arr[][] = {{1, 3, 5},{7,8}};Which of the following print all elements of the array “arr”?*Option 1Option 2Option 3None of above

To determine which option correctly prints all elements of the given 2D array arr, we first need to analyze the structure of the array and understand how elements are stored in a jagged or irregular array.

Break Down the Problem

1. The array arr is defined as a jagged array in C/C++ where the first sub-array has 3 elements and the second sub-array has 2 elements.
2. We need to check each of the options provided to see which one accesses and prints every element of arr.

Relevant Concepts

• Jagged Array: In a jagged array, each sub-array can have a different length.
• Accessing Elements: Each element can be accessed using its index (e.g., arr[i][j]).

Analysis and Detail

Given the array:

int arr[][] = {{1, 3, 5}, {7, 8}};

The expected way to loop through this array and print its elements would look like this in pseudo-code:

for (int i = 0; i < 2; i++) { // Loop through each sub-array
    for (int j = 0; j < length_of_sub_array[i]; j++) { // Loop through elements of the sub-array
        printf("%d ", arr[i][j]); // Print each element
    }
}

Verify and Summarize

To conclude, we need to ensure that one of the options correctly implements a loop structure that accounts for the irregular length of the sub-arrays.

Final Answer

Since the options were not provided, the correct answer would generally be the one that uses nested loops to print each element of arr. If no such options are given, then the answer would be "None of the above." If options were indicated, please provide them for a more precise answer.
