Using the knowledge in computational language in C code it is possible to write a code that organizes and calculates the value of the matrix of A*A and that is in up to 4 decimal places.

<h3>Writing the code in C is possible:</h3>

<em>A=[1 2 2;3 4 5;6 7 8];</em>

<em>[u ,s ,v] = svd(A);</em>

<em>k = 1;</em>

<em>A1 = u(:,1:k)*s(1:k,1:k)*v(:,1:k)'; %'</em>

<em>RMSE = rms(sqrt(mean((A - A1).^2)))</em>

Explain what happens if you try to open a file for reading that does not exist.
ZanzabumX [31]

Answer:

Exception is thrown and the file is created with 0 length.

Explanation:

While opening a file there is an error occur which shows the file does not exist that means an  exception is thrown.

And this error can be occur when the size of the file is very very low means the file is a size of 0 length. So to avoid this error we have to exceed its length from the zero length.

"If a program attempts to modify (or, sometimes, even to read) the contents of memory locations that do not belong to it, the op
Monica [59]

The operating system's memory protection routine intervenes and (usually) terminates the program if a program attempts to modify (or, sometimes, even to read) the contents of memory locations that do not belong to it.

Further Explanation

The memory protection routine is most commonly used in multi-programmed systems to prevent one process from affecting the availability of another. When a user opens up multiple processes, by default, they usually reside at the same time in the main memory. Sometimes, a program may attempt to access, modify, or read memory locations allocated to other processes. When this happens, the memory protection program jumps in. Keep in mind that the memory manager somehow works hand in hand with the memory protection routine. It protects the OS from being accessed by other processes and these processes from accessing one another. In addition, it helps save memory by allocating the same amount of memory to all running processes. The memory protection program, on the other hand, should be able to allow controlled sharing of memory among different processes and will usually terminate a program that tries to modify content of memory locations of that does not belong to it.

A*=++a/6+b++ 3 if a=3,b=4​
Vinil7 [7]

Answer:

a=22.5

Explanation:

Given

a*=++a/6+b++3

Required

The result when a=3 and b=4

Analyzing the given instruction

a*=(++a)/(6)+(b++3)

Single out and solve the expressions in bracket

(++a) = a -- When the ++ operator appears before an operand, it is called pre increment. meaning that the operation will be done before the operand will be incremented.

So: in this case: ++a = a

b++3 = b + 3

The operator, as used in that statement is the same as: b + 3.

So:

a*=(++a)/(6)+(b++3)

a*=(a)/(6)+(b+3)

a*=(3)/(6)+(4+3)

a*=0.5+7

a*=7.5

The above expression is calculated as:

a=a*7.5

So:

a=3*7.5

a=22.5

Svetllana [295]

Answer:

c.

Explanation:

People trust open-source software - if they can see how it works and understand it, they can help improve it and build applications using it. If these protocols were not publicly available - then nobody would have implemented services using them - so nobody would be adopting it.
