#include<stdio.h>

void main()
{
int a,s; /*** local variable****/
printf("\n enter the value of a---");
scanf("%d",&a);
s=a+2;
printf("s=%d",a);
getch();
}



output--

enter the value of a--- 5
s=7




example of global variable----

#include<stdio.h>

int a; /***global variable*********/

void main()
{
int s;
printf("\n enter the value of a--");
scanf("%d",&a);
s=a+3;
printf("\n s=%d",a);

mul(); /****another function********/

getch();


void mul()
{
int m;

m=a*2;

printf("\n m=%d",a);
}


output---
enter the value of a----5

s=8

m=10


///*********************************////

#include main() { char s[] = "Bouquets and Brickbats"; printf(" %c, ",*(&s[2])); printf("%s, ",s+5); printf(" %s",s); printf(" %c",*(s+2)); }
