Basic elements of c language part 2:

we discussed about basic element in c in previous chapter so, we will continue the chapter of basic element in c.

Variable declaration:

if we make any variable then we reserved a specific place in the memory  for the variable. variable declaration is so important because our compiler does not understand anything without declaration.

so we can say that variable declaration is a identity give  to compiler. what i am doing in program.

syntax of variable declaration,

datatype variable name;

for example

void main()

{

int a=5;     // variable declaration

printf("%d",a);

}

Here we can see we declare int type variable which name is a .so in our RAM memory a variable make 2 byte space for storing a particular data.

Statements in c language: 

statement are the command which are given in programs for doing a specific task,  like collect the inputs from the program.

for example:

#include<stdio.h>

 void main()

 {

  int x=6;

  int y=7;

       if(x<y)

        {

            printf("variable x is less than y");

         }

  getch();

  }

if condition(x<y) is true then the statement inside the body will be executed .

there are various types of  statement is given below:

1)labeled statement

2)compound statement

3)iteration statement

4)expression statement

5jump statement

6)selection statement

we will discussed about these statements in details in our next chapter .
