Question

1. Find the errors and correct them. There are at least 5 errors. //This program finds the largest and smallest integer //entered by a user #include using namespace std; int main(){   bool firsttime = true;   int val, min, max;   char userVal;   const char Y;   Y = 'Y';   do;{     cout << "Enter a number:";     cin >> val;     if(firsttime){       max = min = val;       firsttime = false;     }     else(!firsttime){       if(max < val)max = val;       if(min > val){min = val;}     }     cout << "Enter another?";     cin >> userVal >> endl;   }while(Y = userVal);   cout << "Max is:"<< max << " Min is:" << min << endl; }

Explanation / Answer

Here is the program debugged with comments. Find the output as well after that.

#include <iostream> //Error 1: No header file was mentioned//
using namespace std;
int main()
{
   bool firsttime = true;
   int val, min, max;
   char userVal;
   char const Y = 'Y'; // Error 2: char constants must be initialized as and when they are declared //
   //Y = 'Y'; // Hence this line is not required.//
   do // Error3: There was a semicolon here. It is not rquired for 'do' as per syntax //
   {
       cout << "Enter a number:";
       cin >> val;
       if(firsttime)
       {
           max = min = val;
           firsttime = false;
       }
       else if(!firsttime) //Error 4: In case of expression evaluation , it must be within if //
       {
           if(max < val)
               max = val;
           if(min > val)
           {
               min = val;
           }
       }
       cout << "Enter another?";
       cin >> userVal; //Error 5: endl not required while reading a value from console //
   }while(Y == userVal); //Error 6: The operator = was used. In while condition, equality is checked . The operator is == //
   cout << "Max is:"<< max << " Min is:" << min << endl;
}

OUTPUT:

Enter a number: 12
Enter another? Y
Enter a number: 12
Enter another? Y
Enter a number:23
Enter another? N
Max is:23 Min is:12
