C Program Language
Datatypes
A container or memory place to hold data-tems.
Built-in Type
Part of the language construct.
Integer
#include <stdio.h>#include <limits.h> int main(){ printf("Storage size for int : %d \n", sizeof(int)); return 0;}
Signed
int
16 bits
Ex:-32,768 to32,767
short int
8 bits
Ex:-128 to127
long int
32bits
Ex:-2,147,483,648 to 2,147,483,647
Unsigned
long int
32bits
Ex:-2.147,483,648 to 2,147,483,647
short int
8bits
Ex:-128 to 127
int
16 bits
Ex:-32,768 to 32767
Float
#include <stdio.h>#include <float.h> int main(){ printf("Storage size for float : %d \n", sizeof(float)); printf("Minimum float positive value: %E\n", FLT_MIN ); printf("Maximum float positive value: %E\n", FLT_MAX ); printf("Precision value: %d\n", FLT_DIG ); return 0;}
long double
80bits
Ex: 3.4E-4932 to 1.1E+4932
float
32 bits
Character
Character may be an alphabet or a digit or a special symbol. Ex: 'a', '5', '%'
Signed char
8bits
Ex:-128 to127
Unsigned char
8bits
Ex: 0 to255
Char
Double
double
64bits
Ex: 1.7E-308 to 1.7 E+308
Derived Type
Derived from the existing datatypes.
Array
Funtions
Pointer
Reference
User Defined Types
Datatypes defined by the user.
Structure
Union
Enumeration
C- Tokens
Special Symbols (Delimeters)
;,!?#$
Constants & Variables
Numeric Constants

float
%f
Ex: -2.73, 0.71 etc
exponential
12e-2
-1.2E-1
Character Constants
Single
String
Keywords
Identifiers
May be varible or a function name or array varibale.
Strings
Operators
Operators operate on operands.
Arithmetic
Logical
Assignment
Conditional
Special
Increment / Decrement
Bitwise
Relational
Expressions
Arithmetic
precedence
example
Conversions
automatic type
follows the hierarchy of size of the operands
casting a value
(type name)exp;
Mathematical Functions
#include<math.h> cc filename -lm
example
exp(x)
fabs(x)
sqrt(x)
Input/Output
Formatted
Input
scanf("control string", &arg1,&arg2..);
Output
printf("control string", arg1,arg2..);
Unformatted
putchar
putchar(variable_name);
getchar
Control Statements
if
simple if
if else
nested if else
else if ladder
swicth
switch(exp){ case value1:block1; break; case value2:block2; break; ..........default:block; break; } statement-x;
conditional
conditional exp? exp1:true exp2:false
goto
Loops
continue (skip)
for
for(initialize ; test exp ; increment) { body; }
while
while(test exp) { body; }
do.. while
do { body ; } while(test exp);
break (jump)
