Pseudocode Pseudocode - - IF IF Statement Statement BEGIN MAIN CREATE Fahrenheit = 0, Celsius = 0 PRINT Enter Celsius temperature: READ user input Celsius = user input Fahrenheit = 9.0 / 5.0 * Celsius + 32 PRINT Fahrenheit IF (Fahrenheit >= 90) THEN PRINT heat warning ENDIF Ps END MAIN
Example Example - - if if Statement Statement double celsius = 0.0, fahrenheit = 0.0; cout << " What is the Celsius temperature ? "; cin >> celsius; fahrenheit = 9.0 / 5.0 * celsius + 32; cout << "The temperature is " << fahrenheit << " degrees Fahrenheit"; if (fahrenheit >= 90) { cout << "It is really hot out there!"; }
Pseudocode Pseudocode IF IF- -ELSE ELSE Statement Statement BEGIN MAIN CREATE Fahrenheit = 0, Celsius = 0 PRINT Enter Celsius temperature: READ user input Celsius = user input Fahrenheit = 9.0 / 5.0 * Celsius + 32 PRINT Fahrenheit IF (Fahrenheit >= 90) THEN PRINT heat warning ELSE PRINT there is no extreme heat ENDIF END MAIN Ps
Example Example if if- -else (Code Snippet) (Code Snippet) else double celsius = 0.0, fahrenheit = 0.0; cout << " What is the Celsius temperature ? "; cin >> celsius; fahrenheit = 9.0 / 5.0 * celsius + 32; cout << "The temperature is " << fahrenheit << " degrees Fahrenheit"; if (fahrenheit >= 90) { cout << "It is really hot out there!"; } else { cout << "There is no extreme heat today."; }
Pseudocode Pseudocode IF IF- -ELSE ELSE- -IF IF BEGIN MAIN CREATE Fahrenheit = 0, Celsius = 0 PRINT Enter Celsius temperature: READ user input Celsius = user input Fahrenheit = 9.0 / 5.0 * Celsius + 32 PRINT Fahrenheit IF (Fahrenheit >= 90) THEN PRINT heat warning ELSE IF (Fahrenheit >= 80) THEN PRINT it is warm, but there is no extreme heat ELSE IF (Fahrenheit >= 70) THEN PRINT the temperature is pleasant and suggest a picnic ELSE PRINT a suggestion to take a jacket END IF END MAIN Ps
Example Example if if- -else else- -if if double celsius = 0.0, fahrenheit = 0.0; cout << " What is the Celsius temperature ? "; cin >> celsius; fahrenheit = 9.0 / 5.0 * celsius + 32; cout << "The temperature is " << fahrenheit << " degrees Fahrenheit"; if (fahrenheit >= 90) { cout << "It is really hot out there!"; } else if (fahrenheit >= 80) { cout << "It is very warm!"; } else if (fahrenheit >= 70) { cout << "It is very pleasant!"; } else { cout << "It is cool today"; }
Pseudocode Pseudocode switch switch Statement Statement // Read user input like before conditions = compute using Fahrenheit variable / 10 PRINTLINE("It is in the " + conditions + "0's.") SWITCH (conditions) CASE 10: PRINT stay inside , BREAK CASE 9 : PRINT be careful due to heat , BREAK CASE 8 : PRINT it is hot, but not extreme , BREAK CASE 7 : PRINT pack a picnic , BREAK DEFAULT : PRINT take a jacket , BREAK ENDCASE Ps
switch switch Example Example int fahrenheit = 90; int conditions = (int)fahrenheit / 10; cout << "It is in the " << conditions << "0's."; switch (conditions) { case 10: break; case 9: cout << "It is really hot out there!"; break; case 8: cout << "It is warm, but no extreme heat!"; break; case 7: cout << "It is very pleasant today!"; break; default: cout << "Take a jacket!"; break; } cout << "It s hot! Stay inside!";
