2 . Machine Indenpendent:

  ans: It can be run on more than one operating system.

3 . Structured Programming language:

  ans: C is a structured programming language in the sense that we can break the program into parts using functions

4 . Pointers:

  ans: It provide the feature of pointer ,by which we can access the memory.

C Programming Introduction : Tips

 Every C Program Should contain one main functionC Program Execution Always Starts from main.Every c statement must end with semicolon (  ; ).Variable must be declared before use.all c statement can be written in lowercase letter.It is free form-language.

Sample C Program :

//C hello world example #include <stdio.h> void main() { printf("Hello harshup"); } output: Hello harshaup
