Learn and Master C Programming - Introduction to Arrays

The video tutorial covers arrays in C programming, focusing on their declaration, initialization, and usage. It explains 1D arrays, also known as vectors, and 2D arrays, known as matrices. The tutorial demonstrates how to access and modify array elements, providing examples for both 1D and 2D arrays. It emphasizes the fixed size and zero-based indexing of arrays in C.

What is a characteristic of arrays in C?

• They are dynamic in size.

• They are zero-based and fixed in size.

• They are one-based and flexible in size.

• They can store different data types.

How do you declare a one-dimensional array of five integers in C?

• int A{5};

• int A(5);

• int A = {5};

• int A[5];

What is the correct way to initialize an array with values 10, 15, 22, 3?

• int A = [10, 15, 22, 3];

• int A[4] = (10, 15, 22, 3);

• int A = {10, 15, 22, 3};

• int A[4] = {10, 15, 22, 3};

How can you modify the third element of an array to be half its original value?

• A[2] = A[2] * 2;

• A[3] = A[3] / 2;

• A[3] = A[3] * 2;

• A[2] = A[2] / 2;

How do you declare a two-dimensional array with 3 rows and 2 columns?

• int A[3][2];

• int A(3, 2);

• int A{3, 2};

• int A[2][3];

What is the total number of elements in a 3x2 matrix?

• 6

• 2

• 5

• 3

How do you access the element in the second row and first column of a 2D array?

• A[1][1]

• A[2][1]

• A[0][1]

• A[1][0]
