When a function is used as an argument in another function?
It is called callback function. For an example see the qsort function.
What happen when a c program passes an array as a function argument?
When an array name is passed as a function argument, the address of the first element is passed to the function. In a way, this is implicit call by reference. The receiving function can treat that address as a pointer, or as an array name, and it can manipulate the actual calling argument if desired.
What is the name given to the technique whereby a function argument can be modified by passing a pointer to the argument?
Call_by_reference
What does sqrt function return?
square root of the argument
In python are actual and formal parameters matched up by position or name?
When we invoke a function, we pass the actual arguments in the same order specified by the function's formal arguments, thus it is the relative position that determines how they are matched. Note that actual parameter names are within the scope of the calling code while formal parameter names are scoped to the function in which they are declared. The calling code has no access to the formal argument names, and the function may or may not have access to the actual argument names. Python uses the pass-by-object paradigm: if the object being passed is immutable, then it is passed by value (the formal parameter is assigned a copy of the object's value), otherwise it is passed by reference (in which case the formal argument becomes an alternative name for the actual argument).
Which of the argument is not specified in the IF function?
A condition has to be specified. One or both of the True and False arguments can be left out, though you must place a comma after the condition.
What is the range in a function called?
A range specified within a function is known as an argument. The pieces of information that functions require are all known as arguments. These can include ranges or other values.
Why this function is important?
You have not specified any function.
How do you write a Linux function that will go to any directory then ls and pwd on it?
WHAT I NEED DONE in .bash_profile define a function go_show, that willGo to a specific directoryPrint your current locationPrint the contents of your current directoryThe directory this function takes you to will be specified as an argument to the function on the command line. You will need to use a positional parameter to do this
What function will read a specified number of elements from a file in c?
fread() function will read a specified number of elements from a file .
When a function is used as an argument in another function?
It is called callback function. For an example see the qsort function.
What function returns the number of occurrences of a specified character in the input string?
The charAt function returns the number of occurrences of a specified character in the input string.
What are limits in maths?
Limits (or limiting values) are values that a function may approach (but not actually reach) as the argument of the function approaches some given value. The function is usually not defined for that particular value of the argument.
What happen when a c program passes an array as a function argument?
When an array name is passed as a function argument, the address of the first element is passed to the function. In a way, this is implicit call by reference. The receiving function can treat that address as a pointer, or as an array name, and it can manipulate the actual calling argument if desired.
What is a value that is substituted for the independent variable in a relationship or function?
It is called the argument of the function.
What is the name given to the technique whereby a function argument can be modified by passing a pointer to the argument?
Call_by_reference
When argument are passed by value the function works with the original arguments in the calling program?
When a function is passed by value the calling function makes a copy of the passed argument and works on that copy. And that's the reason that any changes made in the argument value does gets reflected to the caller.
