hi,
for more understanding see this program

for adding two no.

#include<stdio.h>................#include<iostream.h>
#include<conio.h> . #include<conio.h>
void main() . void main()
{ . {
int a,b,c; . int a,b;
printf("enter 2 no."); . cout<<"enter two number";
scanf("%d%d",&a,&b); . cin>>a>>b;
c=a+b; . int c=a+b;
printf("sum is=%d"c); . cout<<"sum is="<<c;
getch(); . getch
(); .
} . }

so from above we know that in c variables are declared in
above bt in case of C++ variable declaration can be
anywhere .whenever we need we declare variables
