Answer: While constructing a function the parameters can be passed by value or by reference.
In value parameter we actual make a copy of the values which has been passed to the function from the main method while we reference parameter we copy the address of the values in memory so that while our program references those values it it can refer them from their memory location.
Explanation:
Now we take can example to show parameter passing by value and reference with the help of an C program to add two numbers
int add_val(int x, int y) {
return x + y;
}
void add_ref(int *x, int y) {
*x += y;
}
int main () {
int a, b, c, d;
a = 2;
b = 1;
c = add_val(a,b); //value parameter
d = add_ref(&a, c); // reference parameter
return 0;
}
In the above code the value the value of c is 3 and the value of d is 5. In add_p we have passed the address of the a but in add_val we have passed the values of a and b.
Metadata is the other term for document properties. It is a data that describes another data. The word “meta” means “an underlying definition or description”. Traditionally, it was used in libraries as card catalogs. In digitals, metadata is also used to describe digital data.
Answer:
ICONTEC is the national standards body, and is an active member of the most important international and regional standards bodies. This allows the Institute to participate in the definition and development of regional and international standards in order to be in the vanguard of information and technology.

Answer:
Merge sort is sort, which contains the same elements in the array to maintain original positions concerning each other. Complexity of sort is O (nLogn) and runtime is O(nlogn)
Explanation:
Estimate time spent on presorting an array 101 element in merge and binary search, two schemes can be used in the first scheme if 101 items in sequential search then use the complexity of O(n). In the second scheme covert, the list into an array then sort an array with the complexity of O(n log n) and fetch the 101 elements.
Merge 101 elements; presorted sub-array n items have to compare the top times in sub-array and choose the maximum item and place it in a sorted array. Time for merging is proportional to ( k-1) n.
Suppose the processing time of the merger is c.(k-1) .n then scale factor has the same value.
The processing time of a sorting array is a recurrence equation.
T(n) = 3T (n/3) + 2 cn
Similarly this implement for array of 105 element.
When a program lets the user know that an invalid choice has been made, this is known as a error message.
