Chapter 6 C Program Data Types Constants Variables Pdf Integer It describes the different types of constants in c like integer, real, character, and string constants. it also discusses the rules for identifiers and keywords in c. finally, it explains the primary data types in c including integer, character, floating point, double precision, and void data types. The data type int the basic integral type 2 or 4 bytes 16 or 32 bits, depending upon the machine used to store integers 0, 1, 2, etc. 16 bits: 32768 to 32767 32 bits: 2147483648 to 2147483647.
Lecture 6 Data Types And Variables Pdf Integer Computer Science Program data can be classified according to their types. type information can be contained in a program either implicitly or explicitly. n explicit type information is primarily contained in declarations. variables can be declared to be of specific types. Numeric primitive data • the difference between the various numeric primitive types is their size, and therefore the values they can store: type storage min value max value byte short int long float double. Variable names correspond to locations in the computer's memory. every variable has a name, a type, a size and a value. suppose we want you can do or . evaluated first. if the parentheses are nested, the expression in the innermost pair is evaluated first. To find out the ascii value for any character eg “a” use the following program. main () { printf (“%d”, ‘a’); getch (); } the program will output 97as the output. since each character constant represents an integer value, it is possible to perform arithmetic operations on character constants.

Write an implementation of bubble sort for a xed array of integers. (an array of integers can be de ned as int i[] = {1,2,3,4}; the 2nd integer in an array can be printed using printf("%d\n",i[1]);.) modify your answer to (3) to sort characters into lexicographical order. When you define a variable in c , you must tell the compiler not only what its name is, but also what kind of information it will hold: integer, character, and so forth. this is the variable’s type. another word for type that you may see is datatype. It discusses the history and evolution of c, its key features such as efficiency, portability and modularity. it also describes the structure of a c program including header files, main functions, and comments. finally, it covers c tokens such as keywords, identifiers, constants, variables and data types. Named constants are similar to both literals and variables in that they cannot be changed, but constants can have a data type. constants are usually declared in all caps to distinguish them from variables.
