INTRODUCTION TO LANGUAGES

 Introduction to Languages: The basic components of a computer are: Input unit Central Processing Unit(CPU) Output unit The CPU is further divided into three parts-   Memory unit  Control unit  Arithmetic Logic unit      Most of us have heard that the CPU is called the brain of our computer because it accepts data, provides temporary memory space to it until it is stored(saved) on the hard disk, performs logical operations on it, and hence processes(here also means converts) data into information.       We all know that a computer consists of hardware and software. Software is a set of programs that performs multiple tasks together. An operating system is also software (system software) that helps humans to interact with the computer system.      A program is a set of instructions given to a computer to perform a specific operation. or computer is a computational device that is used to process data under the control of a com...

DECISION MAKING STATEMENTS IN C

Image
  Decision Making Statements : if, if else,nested if, switch statement if STATEMENT if is most basic statement of Decision making statement. It tells to program to execute a certain part of code only if particular condition or test is true. Syntax if(<condition>)     [ Statement or block of statements]; Example #include<stdio.h> #include<conio.h> void main() { int a=9; if(a<10) { printf(“a is less than 10”); } getch(); } Output a is less than 10 Constructing the body of "if" statement is always optional, Create the body when we are having multiple statements. For a single statement, it is not required to specify the body. If the body is not specified, then automatically condition part will be terminated with next semicolon ( ; ). if -else STATEMENT It is a keyword, by using this keyword we can create a alternative block for if part. Using else is always optional i.e, it is recommended to use when we are having alternate block of condition. In any prog...
