Question

I am trying to write simple program using ONLY for loop (if then statement is allowed i think) And I am having trouble getting the highest snow date “calculated” from a bunch of user inputs.

This program writes user input amount of snow that fell on a number of days to a text file. I am supposed to also list the highest snow amount that fell, but don’t (?) know how to do it in the for loop.

for (dayNumber = 1; dayNumber <= numOfSnowDays; dayNumber++)
    {   
        mostSnowDay = dayNumber;
        cout << "Day number:  " << dayNumber << endl;
        cout << "Enter amount of snow: " << endl;
        cin >> amtOfSnow;
        totalSnow = totalSnow + amtOfSnow;
        outFile << setfill(' ') << setw(15) << dayNumber << setw(25) << setprecision(2)   << amtOfSnow << endl;

        if ( dayNumber == 1 )
        {
            mostSnowDay = dayNumber;                             
        }
        else if ( amtOfSnow < mostSnowDay )
        { 
              //dont know what to put here or even if this is right. 
        }

    };

You need some extra variables there:

 if ( dayNumber == 1 )
 {
     mostSnowDay = dayNumber;   // default - most amount of snow in first day  
     mostAmtOfSnow = amtOfSnow; // 
 }
 else if ( amtOfSnow > mostAmtOfSnow ) //if subsequent day has more snow
 { 
     mostSnowDay = dayNumber;     //mark the day
     mostAmtOfSnow = amtOfSnow;   //change largest amount of snow
 }

EDIT: Credit to Dan F. Remove the mostSnowDay = dayNumber; instruction at the beginning of the loop, it will re-initialize your variable each time the loop enters.
