1. Write a C++ program that will prompt the user to input ten integer values.

The program will display the smallest and greatest of those values. It also displays the value that occurs the most.

Solution:

#include <cstdlib> 
#include <iostream> 
using namespace std; 
int main(int argc, char *argv[]) 
{ 
  int arr[10]; 
  int mode[10][2]; 
   cout<<"Enter 10 integer values\n"; 
  for(int l=0;l<10;l++) {

     cout<<"value "<<l<<":";cin>>a[l]; 

} 
 //find the max value and min value
 int i,j,temp;
//sort array to find max and min values
 for(i=0;i<10;i++)
  for(j=9;j>i;j--)
     if(arr[j]<arr[j-1]) {
         int temp=arr[j];
         arr[j]=arr[j-1];
         arr[j-1]=temp;
}
                 
  cout<<"Max="<<arr[9]<<"\nMin="<<arr[0];
  cout<<"\n";
//initialize 2D array storing numbers of occurences, and values
 for(i=0;i<2;i++)
   for(j=0;j<10;j++)mode[j][i]=0;
     mode[0][0]=1;
//find mode
 for(i=0;i<10;i++)
  for(j=0;j<10;j++)
   if(arr[i]==arr[j+1]) {++mode[i][0];mode[i][1]=arr[i];}
  
//find max occurence
int max;
int k=0;
max=mode[0][0];
   for(j=0;j<10;j++)
    if(max<mode[j][0]){max=mode[j][0];k=j;}
   
//print result
  cout<<"The most occurring item:"<<mode[k][1]<<"\n";
  cout<<"It occurs "<<max<<" times.";
  cout<<"\n";
  system("PAUSE");
    return EXIT_SUCCESS;
}

2. Write a C++ program to sort 10 integer values (reading from keyboard) in ascending and descending order.
