Question Using C++ How would you write this without using the FOR statements? #include using namespace std; int main() { int a[20], n, i=0; cout<<"Enter a weight (0 to stop): "<> n; while(n!=0) { a[i] = n; i++; cout<<"Enter a weight (0 to stop): "<> n; } int total =0; for(int j=0;j<i;j++) { total+=a[j]; } double average = total/(double)i; cout<<"The total was "<<total<<endl; cout<<"The average is "<<average<<endl; cout<<"Here are all the numbers less than the average: "; for(int j=0;j<i;j++) { if(a[j]<average) cout<<a[j]<<" "; } cout<<endl; return 0; } Output: Enter a weight (0 to stop): 1 Enter a weight (0 to stop): 2 Enter a weight (0 to stop): 3 Enter a weight (0 to stop): 4 Enter a weight (0 to stop): 5 Enter a weight (0 to stop): 6 Enter a weight (0 to stop): 7 Enter a weight (0 to stop): 8 Enter a weight (0 to stop): 9 Enter a weight (0 to stop): 10 Enter a weight (0 to stop): 0 The total was 55 The average is 5.5 Here are all the numbers less than the average: 1 2 3 4 5
