DATA TYPES IN C? PROGRAMS FOR DATA TYPE

DATA TYPES

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

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.
