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 differen...

DATA TYPES IN C? PROGRAMS FOR DATA TYPE

DATA TYPES

int, float, char
different data types 



  • Data types in C specify the type of data that can be stored in computer memory and also specify the set of values and operations that can be applied to those values.
  • It also specifies the type of data that can be returned, which is a collection of data with fixed values with meaning and characteristics.

DIFFERENT DATA TYPES

  • There are different data types in the c language: The "int" data type is used to store integers, mostly non-decimal numbers for example,-34,56, etc.
  • "Float" data type is used to store decimal numbers, for eg:- 345.6,5.6,34.5, etc. "char" is used to store characters(mostly an alphabet), for eg:-A, c, a, C, j.
  • Now let us see how to write the syntax in a c program, the first step is <data type> which means the type of data that you want to store in the computer memory.
  • We need to specify the second step. Which is to give the space and then say the name of the variable that is with which variable we want to store <name of the variable> so the overall syntax will be <data type>  <name of the variable>.
  •  Int a----->Here int is the data type and a is the name of the variable. 
  • Float b--------> float is the data type, and b is the variable.
  • Char c--------->char data type, and c variable.
  • Note:- semicolon(;) which is the most important thing if we don't use it then it leads to compiler error.
         

FORMAT SPECIFIER:

  • A  format specifier is a string, and the format string starts with the "%" character there are different format specifiers for data types which we are going to learn in this blog.
  • "int" we have the format specifier %d using this we can store only the integer type data.
  • "float"%f  by this we store the decimal values and for "char" that is the character value stores %c.
          int-%d
          float-%f
          char-%c
  • Format specifiers are used in two scenarios, that is while reading data from the keyboard into a variable, and while displaying data stored in a variable onto the console.

PROGRAMS FOR DATA TYPES 

format specifier in c

format specifier
  1. Store 25 in computer memory.
          int n;-------->1st step(declaring the variable).
          n=25; ------->2nd step(assigning the value ).
  • In this example we need to store 25 so we learned before, that to write the syntax in the above lines 25 is without a decimal point take int data type in C.
  • And then give space and write the name of the variable we have given n, and in the next step give the value to the variable that is 25.
          
      2. Store 24.7 

           float a;
           a=24.7;
  • This is similar to the previous question there is a small change. We are using the float data type in C instead of int because 24.7 is the decimal number, we are declaring variable a, and in the next step, we are assigning the value to it.
     3. Store 'a' 
           char n;
           n='a';
  • We are using the char data type because we need to store alphabet values and then declare variable n, and then assign it 'a'. 
    4. Store 56  and display it.
           int  n;-----> 1st line of code
           n=56;------>2 nd line of code
           print f("%d", n);----->3rd line of code
  •  All the previous questions were related to storing from we are going to learn, how to display it after storing so here first and second lines know but the third line needs to use print f.
  •  Within double quotes, the Int format specifier is "%d" after that write the variable which you declared and assigned the value.
   5. Store 4.5 display.
           float n;
           n=4.5;
           printf("%f", n);
  • DATA TYPES IN C, Float has been used because 4.5 is a decimal value and then a variable has been declared and the next step assigned value, displayed it using Printf by using the format specifier and then declared variable.
   6. Store 'z' display.
         char n;
         n='z';
         Printf("%c", n);
  • This is what we studied in this blog the data type in C and the format specifier in the next blogs we are going to study the programs in c language.

BASIC PROGRAM IN C LANGUAGE? INCLUDE, HEADER.

SIMPLE PROGRAM TO PRINT NAMES ON                     CONSOLE USING C LANGUAGE #include <stdio.h> which means that <stdio.h> is the header file that says, that standard input and output header file, so every time there is a format writing the c language program that is the starting line of the code. And Include is the command that we use in the program to include the header file <stdio.h> and this file contains the Printf function means to, display any text onto the console. To use the print function, we need to use #include<stdio.h> then only the print function can be accessed otherwise not.   The first line of the code of the program is, #include<stdio.h> this is the most compulsory step we can say in a c program.                                                    ...

ARRAYS IN C?SCALAR VARIABLE,DISADVANTAGES

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...

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 ...
