Hi, Iam santosh, how can download videos from url like youtube video url or facebook videos urls in java

you are to write a C++ program to generate random
integers in the range [ LOW = 1, HIGH = 10000 ] and to store them in a vector < int > of size
VEC_SIZE = 250. Then, sort the contents of the vector (in ascending order) and display it
on stdout.To sort the contents of a vector, use the sort ( ) function from the STL. In addition to the
main ( ) routine, implement the following subroutines in your program:
• void genRndNums ( vector < int >& v ) : This routine generates VEC_SIZE integers and
puts them in vector v. Initializes the random number generator (RNG) by calling
the function srand ( ) with the seed value SEED = 1, and generates random integers
by calling the function rand ( ).• void printVec ( const vector < int >& v ) : This routine displays the contents of vector
v on stdout, printing exactly NO_ITEMS = 12 numbers on a single line, except
perhaps the last line. The sorted numbers need to be properly aligned on the
output. For each printed number, allocate ITEM_W = 5 spaces on stdout.

hey i want to have google's stock value as it updates in a c# console application how can i do this.

Write a single program that calculates the arithmetic mean (average), rms average, geometric mean
and harmonic mean for a set of n positive numbers. Your program should take two values xlow and
xhigh and generate 10000 random numbers in the range [xlow...xhigh], and should print out arithmetic
mean (average), rms average, geometric mean and harmonic mean.

"Write a program that plays a word game with the user. The program should ask the user to enter the following:

His/her Name

His/her Age

Name of a City

Name of a College

A Profession

A Type of Animal

A Pet's Name

After the user has entered these items, the program shoulld display the following story, inserting the user's input into the appropriate locations:

There once was a person named NAME who lived in CITY. At the age of AGE, NAME went to college at COLLEGE. NAME graduated and went to work as a PROFESSION. Then, NAME adopted a(n) ANIMAL named PETNAME. They both lived happily every after!
