Data Type 3

Let us understand arithmetic instruction:-

An instruction which is used to manipulate the data using operators is known as arithmetic instruction.
In C programming only one variable is allow before = symbol and after this there are no. of variable and constant can be used.
ex: a=b+c;  //correct
      a+b=c;  //incorrect
note:-
      a,b and c are data/operands and +,= is a operator

types of arithmetic instruction:-

1) integer mode:- an instruction in which all  operand are of type int.
             ex:- int a,b,c;
                    a=b+c;
2) real mode:- an instruction in which all are float(real) operand
            ex:- float a,b,c;
                 a=b*c;
3) mixed mode:- an instruction in which some operand are of int type and some are of float type.
            ex:- int a,b;
                    float c,d;
                    a=b*c-d;

Introduction to C

About C:- C is a high-level language . It was initially first developed by D ennis Ritchie in 1972. It was developed to overcome the limitation of previous language such as B,BCPL etc. It was developed for Unix operating System It inherits many features of previous language Features/Advantage:- Simple :- because it provide data types, library function etc. Machine Independent or Portable:- because it can be executed on different machine Procedural language:- Instruction in c program are executed step by step Structured programming language:- break the problem into parts It provide dynamic memory allocation , pointers etc. Speed:-It is faster than another programming language like java, python etc. Disadvantage of C:- It does not support oops concept in which inheritance, polymorphism, encapsulation etc. come. It does not support namespace concept It does not support constructor and destructor There is lack of excepti...

Static Memory Allocation

Statement are of two types:- Declaration:- in which we declare the variable Action:- in which for,if-else,getch,printf,scanf etc are used. SMA(STATIC MEMORY ALLOCATION):-                                whenever we create a program,there is a line of declaration statement(or data type declarartion statement) such as int a;char b;etc. Due to this statement we create a variable a,now this variable is the example of SMA.SMA means how much memory is consumed by variable at the time of compiler,this decision is taken before the compilation. At the compile time these variable such as a and b does not having a memory.Memory is given when program is run i.e when object file convert into .exe file.But when program is run how much memory is taken by the variable is decided at the compilation time.This is known as SMA(Static Memory Allocation).

Identifiers in C

Identifiers are:-  constant variables keywords Define constant:- Any information is constant data = information = constant types of constant primary:- integer,real,character secondary:- they are made with the help of primary such as:- array,string,pointer,union,etc. Define variables:- variables are the name of memory location where we store data variable name is any combination of alphabet,digit the first letter cannot be a digit Keywords:-  keywords are the predefined or reserved words.In C there are 31 keywords.C is a case sensitive so use keyword in small alphabets.
