The code snippet you provided is written in the C++ programming language. It defines a function named f() that performs the following steps:
It declares a pointer variable p of type int*.
It uses the new operator to dynamically allocate an array of three integers on the heap. The initialization of the array is done using an initializer list with three calls to the rand() function. This means that each element of the array will be assigned a random value.
It checks if the value of the second element in the array (indexed as p[1]) is not equal to zero.
The condition p[1] != 0 is a comparison statement. It checks whether the value stored in the second element of the dynamically allocated array is not equal to zero.
If the condition evaluates to true, it means that the second element of the array is not zero. The code does not specify any specific action to take in this case. It would be up to the programmer to add additional code to handle this situation accordingly.
If the condition evaluates to false, it means that the second element of the array is zero. Again, the code does not specify any action to take in this case.
It's worth mentioning that the code you provided does not deallocate the dynamically allocated array, which could lead to a memory leak if the code execution continues without freeing the memory. To avoid memory leaks, it's important to pair each new operator with a corresponding delete[] operator to deallocate the dynamically allocated memory when it's no longer needed.
