This program displays the following output:

As you have just seen, it is possible to access an array by using pointer arithmetic. What you might find surprising is that the reverse is also true. In C++, it is possible to index a pointer as if it were an array. This further illustrates the close relationship between pointers and arrays. Here is an example that indexes a pointer.

Because most organizations will utilize PCs either in full thin-client mode or in hybrid mode, locking down the PCs is critical to keep them from continuing to be an ongoing source of help desk calls. Additionally, these same methods are useful for locking down the published desktop environment of the XenApp farm. Although the tools we recommend for locking down PCs are quite good and will dramatically reduce the administration and maintenance required, desktop hardware failure will still be a cause for lengthy support issues.

tracking down and eliminating the interferers (if possible). Timing is a control issue, and will normally not be your concern. 5. Frequency stability is quite critical for the upstream channel, especially when wideband cable modems are employed as the modulator/demodulators. In these cases, stability must be better than 12 kHz to catch a standard cable modem s preamble (or the link will not lock up), as well as to maintain the BER over time with no automatic reboots. A longer preamble that can tolerate a frequency spec of 25 kHz is possible with some cable modems. 6. Group delay ripple (GDR) must be no more than 75 ns for QAM-64, and less than 200 ns for QPSK, as increased GDR increases ISI. Simple analog design considerations (mainly for the system s bandpass filters) and digital adaptive equalizing will keep GDR in spec. 7. Increased system linearity, through hardware design and/or the appropriate SSPA back-off at the hub and client transmitter, will lessen BER degradation of a digital signal by decreasing intermodulation distortion levels. 8. Multipath causes phase cancellation, which creates both amplitude and phase distortions of the desired signal. This decreases the received signal s strength, thus decreasing SNR and increasing BER. It also creates undesirable amplitude notches or slopes, causing increased ISI. Increasing the gain, and thus the directionality, of the antennas; proper location of the hub transceiver (such as not placing it in front of a tall building or mountain); and using equalizers will all mitigate, but cannot eliminate, multipath problems. 9. Near/far receiver issues can mean some compromises in transmitter and receiver design. Depending on how close a client is to the hub, a close-in receiver may become saturated by the constant power output of the hub transmitter in a multiclient environment. This can be significantly reduced by using receiver front-end attenuators, utilizing the natural shadowing effect created by a high-mounted hub antenna (allowing the close-in receiver to be under the main lobe of the transmitter s antenna), employing different gain antennas for the close-in client receiver to that of the farther out client receiver, or using a switchable front end that will permit the LNA to be bypassed if the client receiver is too close to the hub transceiver. 10. Phase noise created by the nonperfect nature of a real LO will degrade the BER and increase the ISI. A digital wideband client receiver, for example, should possess a phase noise spec 85 dBc/Hz at 10 kHz, or better, to lessen BER degradation of the incoming signal.
