Question

Write a C++ program called min_distance.cpp that reads ten integer numbers from a user and displays the closest distance between two numbers in the numbers. For example, if your program received numbers such as -1, 10, -15, 3, 7, 20, 150, 200, 50, and 4, the answer will be 1 because the distance between 3 and 4 is 1. Note that the distance between two numbers is always positive. The following presents a sample execution of the program:

Enter ten numbers: -1 10 -15 3 7 20 150 200 50 4
Minimum distance is 1 between 3 and 4.

Explanation / Answer

please rate - thanks

#include <iostream>
#include<cmath>
using namespace std;
int main()
{int mat[10][10]={0}, num[10],i,j,min;
int mini,minj;
cout<<"Enter 10 numbers:";
for(i=0;i<10;i++)
    cin>>num[i];
for(i=0;i<10;i++)
    for(j=0;j<10;j++)
        mat[i][j]=abs(num[i]-num[j]);
min=9999999;                          //big number
for(i=0;i<10;i++)
    for(j=0;j<10;j++)
         if(mat[i][j]>0)
              if(mat[i][j]<min)
                  {mini=i;
                  minj=j;
                  min=mat[i][j];
                  }
cout<<"minimum distance is "<<mat[mini][minj]<<" between "<<num[mini]<<" and "<<num[minj]<<endl;
system("pause");
return 0;
}
