Which XXX and YYY correctly output the smallest values? Vector user Vals contains integers (which may be positive or negative).
liubo4ka [24]

Answer:

The answer is "minVal - userVals.at(0); /userVals.at(i) < minVal  "

Explanation:

In the question, it uses minVal instead of XXX to hold the very first arra(userVal) element, and rather than YYY you choose a conditional statement to check which integer is lower than minVal to index of loop increment. It changes the value of the minVal if the condition is valid. It's completely different if we talk about another situation.

You’re trying to cast a video presentation from your tablet to a projector for a training session with some new hires. Although
Vikki [24]

Answer:

Troubleshooting steps to take:

  1. Restart the tablet
  2. Restart the projector

Explanation:

When such problems occur, the basic and quick troubleshooting step is to restart the device or devices involved.

  1. Restart the tablet: This could come in handy regarding this problem. The inability to connect to the projector could be due to the inability of a specific service or driver needed for the projector. Restarting the tablet will load up the drivers and services again to enable smooth connections. When a restart is done, bugs are fixed, internet connection is rectified, memory leaks are stopped, performance is aided, the RAM (Random Access Memory) is flushed or cleaned. This should resolve the problem, however, if not, try number 2.
  2. Restart the projector: There are driver software on projectors, and due to one system failure or another, these software may fail to load. This could affect its connection to another device. As done in (1), restarting the projector will fix those bugs and load up, which should solve the connection issue.
