Answer required
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.
Programming Notes:
• You are not allowed to use any I/O functions from the C library, such as scanf or
printf. Instead, use the I/O functions from the C++ library, such as cin or cout.
• Let v be a vector of integers, then the call: sort ( v.begin ( ), v.end ( ) ) sorts the
elements of v in ascending order. The detailed description of the sort ( ) routine
can be found on the course web site and in the course textbook.
• Execute the srand ( ) function only once before generating the first random
integer with the given seed value SEED. The rand ( ) function generates a random
integer in the range [ 0, RAND_MAX ], where the constant value RAND_MAX is the
largest random integer returned by the rand ( ) function and its value is system
dependent. To normalize the return value to a value in the range [ LOW, HIGH ],
execute: rand ( ) % ( HIGH – LOW + 1 ) + LOW.
