C Programming Language: (Basic)
Hello..
C language is very easy language
than other programming language. It
is very easy to understand this language. To Show any word in Display ..
use printf() and scanf() use for dynamic
input from user.
Firstly
we have to use Header-file ( #include<stdio.h> ) .
This header-file
(#include<stdio.h> ) Use for Standred Input And OutPut.
Example: ( For CodeBlock ) Show Hello World :
#include<stdio.h>
Int
main()
{
printf(“
Hello World “); [ This Command Print
Hello World ]
}
Output:
Hello
World
Example:( C++ Compialor ) Show Hello World
#include<stdio.h>
#include<conio.h>
Int
main()
{
clrscr(); // [ this keyword Use for clear Display ]
printf(“
Hello World “); // [ This Command Print Hello World ]
getch();
}
Output:
Hello
World
Data Type:
Data
types are Integer, charectar , float And Double.
Integer Stored Integer types of
data. Like 1,2,3,4,5,6……….. etc. int represent Integer Types of data.
Character
Stored charectar types of data. Like a,c,b,d,f,g…. etc. char represent
Charecter Types of data.
Float
Stored float types of data. Like 1.02 , 10.44 , 67.98 ,…. etc. float represent
Float Types of data.
Double
Can be Stored Integer and float Types of data with long range than float and
Integer.
Operator :
Operators
symbols are + , - , * , / ,
% etc.
+ Operator Use for Add , - Operator Use for Subtruc , *
operator Use for Multiplication , / Operator use for devided , And % operator
Use For Modulous.
Example:
Example:
( For CodeBlock )
#include<stdio.h>
Int
main()
{
int
a=5,b=2,c;
float d;
c=a+b;
printf(“Add
of two Number is %d + %d = %d ”,a,b,c);
c=a-b;
printf(“\n
Subtruc of two Number is %d - %d = %d ”,a,b,c);
c=a*b;
printf(“\n
Multiplication of two Number is %d * %d = %d ”,a,b,c);
d=a/b;
printf(“\n
Devided of two Number is %d / %d = %f ”,a,b,c);
}
Output:
[ N.B: \n Use for New Line . %d Use to show Integer
data and %f use for Show float Data]
Add
of two Number is 5 + 2 = 7
Add
of two Number is 5 - 2 = 3
Multiplication
of two Number is 5 * 2 = 10
Devided
of two Number is 5 / 2 = 2.5
Loop:
In
Programming We using Loop for repeat a work maney times but get Different Result.
Here we using 3 loops.
i)
For loop
ii)
While loop
iii)
Do while loop.
