2.4 Arrays in c programming

-
Image
  Arrays: - An array is a collection of elements of the same data type stored in contiguous memory locations. It is a derived data type and a homogenous data structure. It is a variable which can store multiple values of the same type under a single variable name, making it easier to manage and manipulate related data. The size of an array is fixed. To access the elements of an array, we use indexes or subscripts accordingly. array index or subscript is used to identify array elements address. Array index or subscript starts with 0 to n-1.   Declaration of an array: - The declaration of an array means telling the compiler to create an array variable and reserving memory for a fixed number of elements of the same data type. Initialization of an array: - Initializing an array means assigning initial values to its elements. Types of arrays: - Arrays are classified based on the number of dimensions they have:             ...

2.1 Control statements in C programming (sequential & conditional)

Control statements in C: - C is a structure-orientated programming language; the statements that are used to control the flow of execution of a program are called control structures. The statements provide a specific order to execute the C program. In C programming, we have four types of control structures. Sequential control structures Conditional control structures Iterative control structures Jumping control structures   1) Sequential control structures: - The C program is a collection of instructions or set of statements which are executed sequentially in a user-specific order. No statement is slipped, and no statement is executed more than once.                   Syntax: -                Flow chart: -                Example: - Output: - 1) Conditional control structures: - It is also known as selection, branchi...

2.2 Control statements ( Iterative or looping control statements)

  3)   Iterative control structures: - Iterative control structure is also called as looping control statements. Looping control statements are used to execute a block of code repeatedly as long as a given condition is true. Instead of writing the same code multiple times, loops help avoid writing repetitive code. Loop declaration and execution can be done in the following ways: Check the condition to start a loop. Initialize the loop with declares a variable. Executing the statements inside a loop. There are three main types of loops in C:                    a)  for loop.                    b)  while loop.                    c)  do while loop.   a) For loop: - For loop a best looping control structure which is used to execute the statement repeatedly as long as a giv...
