why vswr is infinite in short condition?

The ideal case is when ρ is 0, giving a VSWR of 1 or a 1:1 ratio. ... No power is transferred and VSWR will be infinite. With short circuit. Imagine the end of the cable has a short circuit.

A symbol remains undefined when a symbol reference in a relocatable object is never matched to a symbol definition. Similarly, if a shared object is used to create a dynamic executable and leaves an unresolved symbol definition, an undefined symbol error results.

Yes, using explicitly a stack (but recursion is far more pleasant to read, IMHO). In principle it is always possible to remove recursion and replace it with iteration in a language that has infinite state both for data structures and for the call stack. This is a basic consequence of the Church-Turing thesis.

As x → 0, xsin(1/x) → 0 but cos(1/x) oscillates between -1 and 1, so f (x) has no limit as x → 0 and f cannot be continuous at 0.

'if' gets evaluated at runtime and both the blocks if and else are avaliable for execution in the binary. Where as code skipped by #if are ommitted by compiler and not present in the final object code and binary.

To the compiler, there is no difference between the two declarations. ... For example, both of the following statements declare only one pointer. int* ptr, foo, bar; int *ptr, foo, bar; This statement declares multiple pointers, which prevents using the "int*" spacing.

Hi Sarone, Only object references can be null; bytes can be zero, though, as you obviously know, and that's what you meant. In your code snippet, the loop is completely unnecessary; when you allocate the array, all the elements are guaranteed to be zero already.

It means that the file might not exist or some permission error occurred while accessing a file such as "Read-Only" or "Write-Protected", so in those cases fopen will return 0 (a NULL pointer).

According to the man page of vmstat , 'swpd' means the amount of virtual memory used. As my understanding, for most cases it should be zero unless the physical CPU is out of space.

Use typeof anyway with falsy power operator: Using typeof can be a helpful trick, because if a variable is undeclared, then trying to reference it will throw a ReferenceError . But, the typeof an undeclared value is undefined , so using typeof can be a good way to check for null , undefined , and undeclared variables.

Assuming you are talking about x86, the MOVSBL instruction extends a byte (8 bits) representing a signed number to 32-bit signed number. Share a link to this answer.

Infinity is not a real number, and even if it were, it wouldn't be the answer to dividing something by zero. There is no number that you can multiply by 0 to get a non-zero number. There is NO solution, so any non-zero number divided by 0 is undefined.

REAL IS NOT A CORRECT VARIABLE TYPE. The answer to the question is option A)"real" which is not a correct data type. In programming there are various datatype present for storing according to it's need and size. Like "char" is a datatype which is responsible for storing any data which resembles any single character.

Eigenvectors are nonzero by definition, so it must be the case that . Two distinct eigenvalues for the same would mean is somehow stretched by two different amounts. ... The only way this could possibly make sense is if is 0, but eigenvectors are non-zero by definition. So it can't be.

Your replies cleared somewhat of my daughts, according to you, render variable executes only the selected object, while in conditional block, all the blocks are executed.

There are 4 operators that cannot be overloaded in C++. They are :: (scope resolution), . (member selection), . * (member selection through pointer to function) and ?: (ternary operator).

in where clause, you can use functions such as substring, etc. as I know nvl is not working in where clause.
