This Cpp tutorial contains

• Cpp array with random integer values
• Passing array to function
• if statement with in for loop
• Calculate result in function and display

 Compiler used: CodeBlocks Cpp Compiler

Write a program which generates some random number and store in array after it program pass array to a function which calculates maximum and minimum number in array and display it use any Cpp Compiler to code.

How program works

• 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

      Cpp Code

1.  #include <iostream>
2. #include <stdlib.h>
3. using namespace std;
4. void FindMaxMin(int *array, int size)
5. {        int min,max;
6.          min=max=array[0];
7.          for(int i=0;i<size;i++)
8.          {
9.              if(array[i]<min)
10.                min=array[i];
11.             else if(array[i]>max)
12.                max=array[i];
13.          }
14.  cout<<"Minimum Number  = "<<min<<endl;
15.  cout<<"Maximum Number = "<<max<<endl;
16. }
17. int main()
18. {
19.     int array[10];
20.     for(int i=0;i<=9;i++)
21.         {
22.          array[i]=rand()%1000+1;
23.          cout<<"array ["<<i<<"]"<<"= "<<array[i]<<endl;
24.         }
25.     FindMaxMin(array,10);
26. return 0;
27. }
