What is CSS? CSS stands for cascading style sheet. Html and CSS are building blocks of any webpages on the website. They have a big hand behind creative webpage on the internet. By using HTML webpage gets a shape but by using CSS webpage gets a beautiful and attractive look Without using HTML, we can not use CSS but without CSS we can use HTML because CSS applies to the HTML of the webpage. Why use CSS? By using CSS, we can change the font style, font color, background color, background image, control the space between paragraph and much more things which are helping to look webpage attractive for the users. How to code in the CSS? CSS is a computer language that is a very high-level language mean user-friendly language. we can easily learn and be taught CSS language. To write the code of the CSS, we use text editors such as notepad,notepad++, etc, or code editors such as sublime, etc. After writing the code of the CSS, require web browsers(google chrome, firefox, etc) to view on t

 How to find the Armstrong number in the cpp programming language? Here , you will find the solution to the problem to find the Armstrong number in cpp. Following is the code to find the Armstrong number.First,you know  What is Armstrong Number? A positive number which the sum of cube power of every digit is equal to the original number is called the Armstrong number. For example: Armstrong Number Code: #include <iostream> using namespace std; int main() {     int numb, original, rem, result = 0;     cout << "Enter a three-digit integer: ";     cin >> numb;     original= numb;     while (original != 0) {                  rem = original % 10;                  result += rem * rem * rem;                           original /= 10;     }     if (result == numb)         cout << numb << " is Armstrong number.";     else         cout << numb << " is not Armstrong number.";     return 0; } Output: Enter a three-digit integer

 Here, you will find the solution on how to convert the octal number to binary number in the c programming language. Following is the solution to the problem: Code: #include <math.h> #include <stdio.h> int main() {     int octal,original;     printf("Enter an octal number: ");     scanf("%d", &octal);   original=octal;     int deci = 0, i = 0;     long long bini = 0;     // convert octal to decimal     while (octal != 0) {         deci += (octal % 10) * pow(8, i);         ++i;         octal /= 10;     }     int a = 1;    // convert decimal to binary     while (deci != 0) {         bini += (deci % 2) * a;         deci /= 2;         a*= 10;     }         printf("%d in octal = %lld in binary", original, bini);     return 0; } Output: Enter an octal number: 25 25 in octal = 10101 in binary

 Here,we will find the solution of the conversion of the binary to the octal number system in the c programming language. Following is the solution of conversion: Code: #include <math.h> #include <stdio.h> int main() {     long long bina,original;     printf("Enter a binary number ? ");     scanf("%lld", &bina);          original=bina;     int oct = 0, deci = 0, i = 0;     // convert binary to decimal     while (bina != 0) {         deci += (bina % 10) * pow(2, i);         i++;         bina /= 10;     }     int j = 1;     // convert to decimal to octal     while (deci != 0) {         oct += (deci % 8) * j;         deci /= 8;         j *= 10;     }  printf("%lld in binary= %d in octal", original, oct);    return 0; } Output: Enter a binary number ? 10101 10101 in binary= 25 in octal

In this example,we will discuss how to convert octal to decimal number system in the c programming language. Following is the solution to the problem. Code: #include <stdio.h> #include <math.h> using namespace std; int main() {    int octalNumber,originalnumber;     printf("Enter a octal number: ");     scanf("%d", &octalNumber);   originalnumber=octalNumber;     int decimalNumber = 0, i = 0, remainder;     while (octalNumber != 0)      {            decimalNumber += (octalNumber%10) * pow(8,i);         ++i;         octalNumber/=10;     }      printf("%d in octal = %d in decimal", originalnumber, decimalNumber);    return 0; } Output: Enter a octal number: 74 74 in octal = 60 in decimal  

 In this example,we will discuss about how to convert decimal to octal in the c programming language.Following is the solution of the problem. code: #include <stdio.h> #include <math.h> using namespace std; int main() {    int deciNumber,originalnumber;     printf("Enter a decimal number: ");     scanf("%d", &deciNumber);   originalnumber=deciNumber;     int octalnumber = 0, i = 1, remainder;     while (deciNumber != 0)      {            remainder = deciNumber % 8;         deciNumber /= 8;         octalnumber += remainder * i;         i *= 10;     }      printf("%d in decimal = %d in octal", originalnumber, octalnumber);    return 0; } Output: Enter a decimal number: 60 60 in decimal = 74 in octal

 In this example, we will learn how to convert decimal to binary number system in a c programming language. Following is the solution to the problem. Code: #include <math.h> #include <stdio.h> int main() {     int num,original;     printf("Enter a decimal number: ");     scanf("%d", &num);     original=num;      long long binary = 0;     int remainder, i = 1;     while (num != 0) {         remainder = num % 2;         num /= 2;         binary += remainder * i;         i *= 10;     }     printf("%d in decimal = %lld in binary", original, binary);     return 0;    } Output: Enter a decimal number: 15 15 in decimal = 1111 in binary
