Question

LessThan Program. Write a C++ program that include a function named LessTan. The function accepts two arguments: an integer vector named numberList with ten elements and an integer number x. In the function, display each element of the given array first using a loop.  Then, if there are anynumbers in the given array that are less than x, display those numbers (it’s permitted to contain duplicate values);otherwise, display a message: “No numbers in the array are less than x.”.

 

Here is the function header:

 

void LessThan(vector<int> list, int x)

 

In the main() function, prompt user to enter the number of random numbers that they want to generate. Then use a loop to creates those random numbers each between 0 and 9 inclusive and stores them in numberList. The main function then prompts the user to enter an integer between 0 and 9 inclusive. Pass the numberList vector and user input number as arguments to call LessThan() function.

To generate a random number ranNum between minValue and maxValue, use the following statements:

//get the system time

unsigned seed = time(0);

//seed the random number generator

srand(seed);

      int ranNum = rand() % (maxValue – minValue + 1) + minValue;

 

Note: the time() function requires <ctime> header file; the rand() function requires

<cstdlib> header file.

After writing the code for each problem, debug and test your program to make sure there is no syntax and logical errors. Generate a testing report to show at least two testing cases and outputs for the lab program.
