Answer:
=IF(D3>50; E3; F3) AND =IF(A1>60;"Pass";"Fail")
Explanation:
An IF structure is built following this pattern:
IF(TEST;IFTRUE;IFFALSE)
These are the only options in the given drop-down menus what comply with this pattern. All others are not following this pattern.
The computer will do the test and if the result is true will apply the IFTRUE value, otherwise will apply the IFFALSE value.
Answer:
The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).
The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.
So, while copying data, it is important to always limit the maximum amount to the allocated space.
Answer:
He was not born into a family of skilled laborers
Explanation:
Mechanical mouse has a ball that turns rollers inside. If friction is lost between the ball and the mousing surface, or between the ball and the rollers, the mouse fails to work. In order to assure good contact with the mousing surface, the ball must be fairly heavy. When you change directions with the mouse, you must make the ball change rolling directions--an action that inertia likes to prevent.
An optical mouse makes use of an LED and some optics to detect surface texture and the changes in it as the mouse is moved. There are no moving parts
