TUTORIAL IT

• Declare array of size 10
• Using for loop assign array indexes with random values between 1 and thousand
• Call the function and pass array and its size as argument
• Function declares two integers max and min and assign both integers with arrays first index value
• Then with in for loop there are two if condition first check is for minimum number and second check is for maximum number
• Finally program display the output values of both integers min and max

#include <iostream.h>
#include <stdlib.h>

void FindMaxMin(int *array, int size)
{
     int min,max;
            min=max=array[0];
            for(int i=1;i<size;i++)
            {
                 if(array[i]<min)
                    min=array[i];
                else if(array[i]>max)
                    max=array[i];
            }
 cout<<"Minimum Number  = "<<min<<endl;
 cout<<"Maximum Number = "<<max<<endl;
}
int main()
{
     int array[10];
     for(int i=0;i<=9;i++)
        {
            array[i]=rand()%1000+1;
         cout<<"array ["<<i<<"]"<<"= "<<array[i]<<endl;
          }
     FindMaxMin(array,10);
return 0;
