Question

Write a C++ program without using more than one variable and a pointer variable, to repeatedly obtain float type numbers until -1 is entered, to store them in contiguous memory cells, and to compute their average and print it.

explain your solution

Answer 1

#include <iostream>

using namespace std;

int main()
{
float n;
float sum=0.0;
int count=0;
do{
cout<<"enter floating point number"<<endl;
cin>>n;
if(n==-1){
cout<<"average of floating numbers is:"<<sum/count<<endl;
break;
}
else{
sum+=n;
count++;
}
  
}while(n!=-1);

return 0;
}

/* comments

first of all we use a do while loop for accepting user input as float value...when user enters the input firstly it checks it is -1 or not ..if it is not -1 then the value is added to sum and counts the number of input ..and when ever we encounter -1 it computes avearage of all numbers
