Q.No.2

a. Rewrite the following code after removing the syntax error if any. Underline the correction 

            #include <iostream.h>

             jampto(int, int )

               void main()

                 {

                     first=10, second=20;

                     jumpto(first;second);

                     jumpto(second);

                 }

               void jumpto(int n1, intn2=20)

                      {

                             n1=n1+n2;

                     }

      (b) Find the output : 

             void result(int &x, int y=10)

                  {

                      int temp = x + y;

                      x + = temp;

                      if(y <=10)

                      y + = temp;

                  }

             void main( )

              {

                 int A1=10, B2=5;

                 result(A1, B2);

                 cout<<A1<<B2<<endl;

                 result(A1);

                 cout<<A1<<B2<<endl;

                 result(B2);

                 cout<<A1<<B2<<endl;

            }

       D. Find the output 

             #include <iostream.h>

                void main( )

                   {

                          int i = 0, x = 0;

                         do

                             {

                                 if(i % 5 = = 0)

                                      { cout<<x;

                                             x++;

                                      }

                                      ++ i;

                            }while(i<10);

                            cout<<”\n”<<x;

                   }

      e. Find the correct possible output 

             void main()

               {

                 randomize();

                 char city[][10]={“del”,”chn”,”kol”,”bom”,”bng”};

                int fly ;

                 for(int i=0;i<3;i++)

                     {

                           fly = random(2)+1;

                           cout<<city[fly]<<”:”

                     }

                }

Output:-

      1. Del:chn;kol

      2. Chn:kol:chn

      3. Kol:bom:bng

      4. Kol:chn:kol
