How to rewrite this code using "For Loop" format?

===========================================================

#include<iostream>

#include<cmath>

#include<cstdlib>

using namespace std;

int main()

{

//declaring vars

double sum,

Value,

Max,

Min,

BestValue,

Uncertainty;

int count = 0;

char loop_test;

do // input

{ cout<<"Type in a lab data:";

cin>>Value; //cout<<" The lab result of"<<Value<<"is"<<endl;

if ( count == 0)

{

Max = Value;

Min = Value;

}

if (Value < Min)

Min = Value;

if (Value > Max)

Max = Value;

sum += Value;

count ++;

cout<<" Another? Type Y for yes";

cin>>loop_test;

}while(loop_test=='y'||loop_test=='Y');

cout<<endl;

// output

Uncertainty = (Max - Min)/count;

BestValue = sum / count;

cout << fixed;

cout.precision(2);

cout << " max" << Max;

cout <<" min " << Min;

cout << " count " << count << endl;

cout<<"Physics 4AL Laboratory Results:";

cout<<"Distance = "<<BestValue<<" +&- "<<Uncertainty<< endl;

return 0;

}

Explanation / Answer

Answer:

int count; char loop_test = 'y';

for (count=0; loop_test=='y' || loop_test=='Y'; count++)

{

bla bla bla....

}

In place of bla bla bla..., you just type exactly same thing as inside the do while loop

Except, do not write the count++; statement. Everything before and after should be same.

The for loop structure is :

for (initialize; condition; update)

{

bla bla bla....

}

The do while structure is :

initialize;

do

{

bla bla bla..... update;

}

while (condition);

In your example, condition is loop_test=='y' || loop_test =='Y'

Initialize is count = 0 and update is count++

So the code is :

#include<iostream>

#include<cmath>

#include<cstdlib>

using namespace std;

int main()

{

//declaring vars double sum, Value, Max, Min, BestValue, Uncertainty; int count;

char loop_test = 'y';

for (count=0; loop_test=='y' || loop_test=='Y';coint++)

// input { cout<<"Type in a lab data:"; cin>>Value;

//cout<<" The lab result of"<<Value<<"is"<<endl;

if ( count == 0) { Max = Value; Min = Value;

}

if (Value < Min) Min = Value;

if (Value > Max)

Max = Value;

sum += Value;

cout<<" Another? Type Y for yes";

cin>>loop_test;

}

cout<<endl; // output Uncertainty = (Max - Min)/count;

BestValue = sum / count;

cout << fixed; cout.precision(2);

cout << " max" << Max;

cout <<" min " << Min;

cout << " count " << count << endl;

cout<<"Physics 4AL Laboratory Results:";

cout<<"Distance = "<<BestValue<<" +&- "<<Uncertainty<< endl;

return 0;

}
