What is the difference between the two files. file1.c# include...........int i;void main(){..........}file2.c# includestatic int i;void main(){....}

Question:What is the difference between the two files. file1.c# include...........int i;void main(){..........}file2.c# includestatic int i;void main(){....}?

Answer: </P><P>While in this case for both the programs... the scope and lifetime of variable &#39;i&#39; is throughout the program..... the value of &#39;i&#39; is not. For eg. if &#39;i=2&#39; in the file1.c, any other program accessing this variable from outside will still see the value of i as 2. Whereas in File2.c if the variable &#39;i&#39; is accessed from any other program its value will always be seen as 0</P><P>Reason: For static variables their values are active only within the COMPILE AREA of where it is declared or in the program where it is declared.
