Hi Anya, your code is full of syntactical errors. Rectified cde is as follows:
#include <iostream>
using namespace std;
int main() {
int a[4]; // Array of size 4
int *p; // Pointer to integer
p = a; // Assign the address of the first element of array 'a' to pointer 'p'
*p = 10; // Set the value at the memory location pointed to by 'p' (i.e., a[0]) to 10
p++; // Move pointer to the next element in the array
*p = 20; // Set the value at the memory location pointed to by 'p' (i.e., a[1]) to 20
p = &a[2]; // Set pointer 'p' to point to the third element of the array 'a'
*p = 30; // Set the value at the memory location pointed to by 'p' (i.e., a[2]) to 30
// Loop to print the first three elements of the array
for (int i = 0; i < 3; i++) {
cout << a[i] << " , "; // Print the array values followed by commas
}
return 0;
}
Output:
10 , 20 , 30 ,
