  • Problem 4.
    Write a C++ program that generates three integer random numbers in the range 0 .. 10.

  • Problem 5.
    Write a C++ program that finds the smallest and largest number in an array of double . Use a function 
    void sl(double* array,double& largest,double& smallest,int size)
    to do the job. Here size is the size of the array.

  • Problem 6.
    Write a C++ program that finds the position of the smallest and largest number in an array of double . Use a function 
    void slposition(double* array,int& plargest,int& psmallest,int size)
    to do the job. Here size is the size of the array.
