continued.... In C++ an array variable is actually a pointer variable that points to the first indexed variable of the array. Given the following two variable declarations, p and a are the same kind of variable: int a[10]; #def int* IntPtr; IntPtr p; * The fact that a and p are the same kind of variable. Since a is a pointer that points to a variable of type int (namely the variable a[0]), the value of a can be assigned to the pointer variable p as follows: p = a; After this assignment, p points to the same memory location that a points to. So, p[0], p[1], … p[9] refer to the indexed variables a[0], a[1], … a[9]. The square bracket notation you have been using for arrays applies to pointer variables as long as the pointer variable points to an array in memory » You cannot change the pointer value in an array variable, such as a. 1 //Program to demonstrate that an array variable is a kind of pointer variable. 2 #include <iostream> 3 using namespace std; 4 5 #def int* IntPtr; 6 7 int main( ) 8 { 9 IntPtr p; 10 int a[10]; 11 int index; 12 13 for (index = 0; index < 10; index++) 14 a[index] = index; 15 16 p = a; 17 18 for (index = 0; index < 10; index++) 19 cout << p[index] << " "; 20 cout << endl; 21 22 for (index = 0; index < 10; index++) 23 p[index] = p[index] + 1; 24 25 for (index = 0; index < 10; index++) 26 cout << a[index] << " "; 27 cout << endl; 28 29 return 0; 30 } #what_is_the_output_of_these_program? https://t.me/+txk6Ik_UwGc4ZGM0 https://t.me/+txk6Ik_UwGc4ZGM0
