WHAT IS CSS?ADVANTAGES, SYNTAX.

 CSS PROGRAMMING LANGAUGE                                                                     disadvantages CSS full form is cascade style sheets , which we call it says about how you should display the HTML elements on the screen. CSS tells us the style of the webpage let us take a simple example, if we build a home first we lay out the design that is known as the HTML language. Where the CSS means layout which means giving instructions on how the furniture should be nothing but the CSS. For example if we take PayPal we can see that the background color blue says the CSS background-color property. Netflix is also the best way of saying  CSS property, but if we remove it will be a normal webpage but with the red color and the black plus symbols it looks like the best webpage. Versions of CSS There are different versions available now in case it is developed by Wium we have three versions that are css1, css2, and css3. Currently we are using this css3 version this is the best version fo

ARRAYS IN C?SCALAR VARIABLE,DISADVANTAGES

SCALAR VARIABLE:-

                                                     
array




  • A scalar variable is that which can hold only one value it is known as a scalar variable.
  • For eg:-int a=10;
                         a=30;

DISADVANTAGES OF SCALAR VARIABLE:-    

  • Whenever multiple data items are required to be in the computer memory and access those data items scalar variables have 2 limitations: increase code and performance problems.

AGGREGATE VARIABLE:-

  • A variable that can hold multiple values(data items) is known as an aggregate variable.

WHAT IS AN ARRAY:-

  • An array is an index-based collection of homogenous elements, the array is a collection of  (continuous) memory locations referred to by a common name that can hold multiple values.
  • Is a subscripted variable that can multiple data items of the same data type and it is an aggregate variable.
  • Whenever multiple data items of the same type are required to be stored in computer memory we go for an array, for eg:-marks of all the students of a class, salaries of all the employee's company.

DECLARING ARRAY:-

  • <DATA TYPE>  <IDENTIFIER>[SIZE];   declaring an array means first we need to specify the data type whether it is int, float, char, and give space, declare the variable and size.
  • For eg:-int a[5]; in the above example, an integer array of size 5 is created.
  • The first index of an array is nothing but its lower bound, always it is 0, the last index of an array is its upper bound, it is n-1 where n is the size of the array.
  • In the above diagram, the lower bound is 0 and the upper bound is 4 because we declared 5 as the size(5-1).

  PROGRAM ON ARRAY:-  Store the first ten natural numbers in an integer array.

  #include<stdio.h>
 #define size 10//named constant
 void main()
 {
  int n[size];
  int i;//loop counter
 for(i=0;i<size;i++)
{
  n[i]=i+1;
}
for(i=0;i<size;i++)
{
printf("%d\n",n[i]);
}https://www.geeksforgeeks.org/advantages-and-disadvantages-of-array-in-c/
}//main

PROGRAM:-To store even numbers of the first 10 natural numbers into an array and display.

#include<stdio.h>
#define size 5//named constant created
void main()
{
  int n[size];
  int i;//loop counter
  for(i=0;i<size;i++)
 {
  n[i]=2*(i+1);
  }
 for(i=0;i,size;i++)
 {
 printf("%d\n",n[i]);
 }
}//main

PROGRAM:-Read the marks of 5 students from the keyboard store in computer memory and display the same.


#include<stdio.h>
void main()
{
 int m[5];
 int i;
 for(i=0;i<5;i++)
 {
  printf("enter student %d marks:",i+1);
  scanf("%d",&m[i]);
 }
 for(i=0;i<5;i++)
{
 printf("student %d marks %d\n",i+1,m[i]);
 }
}//main

PROGRAM:-Store the first 10 natural numbers into an array and display the elements of the array in reverse.


#include<stdio.h>
void main()
{
 int n[10];
 int i;
 for(i=0;i<10;i++)
{
 n[i]=i+1;
 }
for(i=0;i>10;i--)
{
printf("%d\t",n[i]);
}
}//main

ONE-DIMENSIONAL ARRAY:-An array that has a single subscript for eg-int a[10];
in a single-dimensional array, elements are stored in a linear fashion.

#include<stdio.h>
void main()
{
 int a[5]={10,20,30,40,50};
 int b[5];
 int i;
 for(i=0;i<5;i++)
 {
  b[i]=a[i];
  }
 printf("elements of the first array.....\n");
 for(i=0;i<5;i++)
 {
  printf("%d\t",a[i]);
 }
 printf("\n elements of the second array...\n");
 for(i=0;i<5;i++)
 {
  printf("%d\t",b[i]);
 }
}//main
 
PROGRAM:-Initalize an integer array with 5 numbers, interactively search for an element in the array.

#include<stdio.h>
void main()
{
 int a[5]={10,20,30,40,50};
 int n;
 int i;
 int flag=0;
 printf("enter the number to search in the list:");
 scanf("%d",&n);
 for(i=0;i<5;i++)
{
 if(n==a[i])

 flag=1;
 break;
}
}
if(flag)
printf("%d is found at the index %d in the list",n,i);
else 
printf("%d is not found in the list");
}

TWO-DIMENSIONAL ARRAY:-
  • An array that has 2 subscripts is nothing but a two-dimensional array.
  • First subscript represents the number of rows and second represents the number of columns, a two-dimensional array represents data in a tabular/matrix format.

#include<stdio.h>
void main()
{
 int n[2][2]={{10,20},{30,40}};
 printf("%d\t",n[0][0]);
 printf("%d\n",n[0][1]);
 printf("%d\t",n[1][0]);
 printf("%d",n[1][1]);
}

  •  In the previous blogs we read about operators and their types including arithmetic,  assignments.

WHAT IS C LANGUAGE? USES, COMPILER

C LANGUAGE C language compiler, C is one of the most popular languages in programming,  Dennis M.RITCHIE invented C programming in the year the 1970s,  C is a high-level programming language which means, its instructions are away from the understanding of the processor. There is a small difference between C language and C++ that is c does not provide object-oriented support. C++ gives class-based support(ORS) which means the same as the previous line in this blog. WHY LEARN C  LANGAUGE Learning C language and a compiler will be useful for coding. Especially for making a website with C language. If we learn C++ it will be useful for making a website. This means C language is only used for making a website but C++ is used for adding colors background colors etc. C language is one of the straightforward languages means easily understandable language. USES OF C LANGUAGE While the C language is used, in the creation of hardware devices.  It is also used in the OS, that is the operating sy

OPERATORS IN C?ARITHMETIC, ASSIGNMENT....

  O PERATORS IN C                                                                  operators A n op erator is a symbol that acts on data items known as operands in order to process them.   for eg-   a+b   ( "a" and "b" are operands, and "+" is an operator ).               c-a     ( " c "&"a"  both are operands "-" operator ).    We can do addition, subtraction, multiplication, division, etc........ Operand and the operator plays a very important role in the programming language. CLASSIFICATION OF OPERATORS B ased number of operands operating upon, operators are classified into three types. Unary operators(operate upon single operand). Binary operators(operate upon two operands). Ternary operators(three operands). On the type of execution they perform on the operands, operators are classed  into six types Arithmetic operator :-arithmetic operators are the operators which perform addition( + ), subtraction( - ), multipli

FUNCTIONS IN C?CLASSIFICATION, PARAMETERS, LOCAL VARIABLE.

 WHAT IS A FUNCTION                                                                         function A self-contained, named block of code that performs the specific task when called is nothing but a function. Note:-functions are the task performers in C projects.  FUNCTIONS CLASSIFICATION We have 2 types of functions they are user-defined functions and library functions. A pre-created function that comes with C installation is nothing but a library function, For eg:- print () and scanf(). Library functions are ready-made named code blocks. We need not create them, Just use them in our programs. We can make use of this library function by making the library function available to the program and the next step is calling the library function. Our own created function which is the program-created function is nothing but a user-defined function , eg- the main function is the example of a user-defined function. BENEFITS OF USER-DEFINED FUNCTION There are many benefits of user-defined func
