NOTE: Refer the previous programming project 10. 

Modified program code:

//header file

//Program begins from the main method
int main()
{
    //Define variables
    double inputNums;
    double sumOfPositiveNums=0;
    double sumOfNegativeNums=0;
    double totalOfAllNums=0;
    double totalPosNums=0;
    double totalNegNums=0;
    //Readsten whole numbers 
    cout<<" Enter any 10 numbers(whether positive, negative, or zero): "
    <<endl;
    for(int i=0;i<10;i++)
    {	
	    cin>>inputNums;
	    
	    totalOfAllNums +=inputNums ;
	   if(inputNums>0)//validate negative
	   {
            sumOfPositiveNums += inputNums;
            totalPosNums++;
	   }
       else
       {
	        sumOfNegativeNums += inputNums;
	        totalNegNums++;
       }
    }
    //Print sum of all positive numbers
    cout<<"Sum of all the POSITIVE numbers: "
         <<sumOfPositiveNums<<endl;
    cout<<"AVERAGE of all positive numbers : "
        <<sumOfPositiveNums/totalPosNums<<endl;
    //Print sum of all negative numbers
    cout<<"Sum of all the NEGATIVE numbers: "
         <<sumOfNegativeNums<<endl;
    cout<<"AVERAGE of all negative numbers : "
        <<sumOfNegativeNums/totalNegNums<<endl;
    //Print total sum of numbers
    cout<<"The sum of all the numbers : "<<totalOfAllNums<<endl;
    cout<<"Average of ALL NUMBERS: "<<totalOfAllNums/10<<endl;

}
