Suppose int arr[]={10,20,30};
calculate base address:
treat base address as 500
arr[1]=*(arr[0]+1);
i.e,*(500+1)=*(502)
so 502 pointing to element 20.so arr[1]=20
like wise......
arr[0]=10;
arr[2]=30;

What is first element address?

@Poonam.
Base address is the address of list element of the array.
If we pass only name of the Array to a function, it basically means that The base address is passed.

Base address of the array and array passing by reference are same or different.

When we passing a hole array as argument like:
getArray(int formal[])
{
int i;
for(i=0;i<12;i++)
{
scanf("%d",&formal[i]);
}
return (formal)
}
main
{
int Array[12];
getArray(Array);
for(i=0;i<12;i++)
{
printf("%d\n",Array[i]);
}
getch();
}
--------------------------------------
In getarray(array); ... which technique we are using call by value or call by reference ?
getArray(int formal[])
{
int i;
for(i=0;i<12;i++)
{
scanf("%d",&formal[i]);
}
return (formal)
}
main
{
int Array[12];
getArray(Array);
for(i=0;i<12;i++)
{
printf("%d\n",Array[i]);
}
getch();
}

Base address same as first address of array element?

Write a program that reads values into an array from a file and sorts the data and writes it in a file.
Help me out with this.

When we pass the array name of a 2-d array as an argument to a function and store the address in a integer pointer in the function, the compiler shows an error "10 C:\Users\DJ\Documents\devc\pointerarray.cpp cannot convert `int (*) [4]' to `int*' for argument `1' to `void display (int*, int, int) ' ".
