Arrays 

Properties of Arrays in C
It is very important to understand the properties of the C array so that we can avoid bugs while using it. The following are the main properties of an array in C:

1. Fixed Size
The array in C is a fixed-size collection of elements. The size of the array must be known at the compile time and it cannot be changed once it is declared.

2. Homogeneous Collection
We can only store one type of element in an array. There is no restriction on the number of elements but the type of all of these elements must be the same.

3. Indexing in Array
The array index always starts with 0 in C language. It means that the index of the first element of the array will be 0 and the last element will be N – 1.

4. Dimensions of an Array
A dimension of an array is the number of indexes required to refer to an element in the array. It is the number of directions in which you can grow the array size.

5. Contiguous Storage
All the elements in the array are stored continuously one after another in the memory. It is one of the defining properties of the array in C which is also the reason why random access is possible in the array.

6. Random Access
The array in C provides random access to its element i.e we can get to a random element at any index of the array in constant time complexity just by using its index number.

7. No Index Out of Bounds Checking
There is no index out-of-bounds checking in C/C++, for example, the following program compiles fine but may produce unexpected output when run.

 25 day Create a Function To create (often referred to as declare) your own function, specify the name of the function, followed by parentheses () and curly brackets {}: Syntax void myFunction() {   // code to be executed }

 26 day  Call a Function Declared functions are not executed immediately. They are "saved for later use", and will be executed when they are called. To call a function, write the function's name followed by two parentheses () and a semicolon ; In the following example, myFunction() is used to print a text (the action), when it is called: Example Inside main, call myFunction(): // Create a function void myFunction() {   printf("I just got executed!"); } int main() {   myFunction(); // call the function   return 0; }

 42 day  C Structures The structure in C is a user-defined data type that can be used to group items of possibly different types into a single type. The struct keyword is used to define the structure in the C programming language. The items in the structure are called its member and they can be of any valid data type. Additionally, the values of a structure are stored in contiguous memory locations. Syntax struct structure_name {     data_type member_name1;     data_type member_name1;     ....     .... };
