Concept of Array An array is a collection of data items, all of the same type, accessed using a common name. A one-dimensional array is like a list; A two dimensional array is like a table; The C language places no limits on the number of dimensions in an array, though specific implementations may 2. One Dimensional Array A one-dimensional array is a structured collection of components (often called array elements) that can be accessed individually by specifying the position of a component with a single index value. Syntax: data-type arr_name[array_size]; Initialization of One-Dimensional Array in C An array can be initialized at either following states: 1. At compiling time (static initialization) 2. Dynamic Initialization Compiling time initialization: The compile-time initialization means the array of the elements are initialized

Types of Flow Control Statements 2. if Statement 3. if...else Statement 4. if...else if Ladder 5. switch case Statement 1.Types of Flow Control Statements There are four types of control statements in C: • Decision making statements. • Selection statements. • Iteration statements. • Jump statements. 2.if Statement An if statement consists of a Boolean expression followed by one or more statements. Syntax The syntax of an 'if' statement in C programming language is − if(boolean_expression) {    /* statement(s) will execute if the boolean expression is true */ } If the Boolean expression evaluates to true, then the block of code inside the 'if' statement will be executed. If the Boolean expression evaluates to false, then the first set of code after the end of the 'if' statement (after the Closing curly brace) will be will be executed.C programming language assumes any non-zeroFlowDiagram 3.if...else S

Relational Operators In computer science, a relational operator is a programming language construct or operator that tests or defines some kind of relation between two entities. ... In languages such as C, relational operators return the integers 0 or 1, where 0 stands for false and any non-zero value stands for true   Logical Operators     Operator Description Example && Called Logical AND operator. If both the operands are non-zero, then the condition becomes true. (A && B) is false. || Called Logical OR Operator. If any of the tw

Storage Classes structure of a c program Before we study the basic building blocks of the C programming language, let us look at a bare minimum C program structure so that we can take it as a reference in the upcoming chapters. Hello World Example A C program basically consists of the following parts − • Preprocessor Commands • Functions • Variables • Statements & Expressions • Comments Let us look at a simple code that would print the words "Hello World" − #include <stdio.h> int main() {    /* my first program in C */    printf("Hello, World! \n");    return 0; } Let us take a look at the various parts of the above program − · The first line of the program #include <stdio.h> is a pr
