Answer 1

Note: In the question, it not specified the language like c, c++ or java, etc so I write the c++ syntax

Write a loop to print a list of numbers starting at 64 and ending at 339. Justify your syntax.

for (int i = 64 ; i<= 339 ; i++)  // Here is for loop which starts from 64
                                    // and runs upto 339
     
      {
          cout<<i<<endl;            // output statement to print the value of i
      }

2. Write a switch statement that uses the colour of a swab sample of COVID testing vehicle to send a message to a local doctor. Use the messages given for each colour in the table below. Justify your answer.

Colour Message

switch(colour) // Here we make the switch statement and take color as an argument for matching case 
            
    {
      
      case Blue:              // if colour is blue the case blue will be executed
      cout<<"No virus"<<endl; // Here is output statement to print result of colour
      break;                  // Here is break statement to break the switch case after find the match
       
     
      case Yellow:             // if colour is Yellow the case blue will be executed
      cout<<"Needs to be under observation"<<endl; // Here is output statement to print result of colour
      break;                   // Here is break statement to break the switch case after find the match
    
      
      case Red:                 // if colour is red the case blue will be executed

      cout<<"Need to be admitted in COVID ward"<<endl; // Here is output statement to print result of colour

      break;                   // Here is break statement to break the switch case after find the match
     
      default:                 // Here is the default case for wrong input other than the desired input
      break;                   // Here is break statement which break the further operation 
                               // and get you out out of the switch statement
    } 

Note: Justification of each line of syntax wrote in front of that line after the double forward slash
