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 differen...
SCALAR VARIABLE:-
- 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]);
}
