Question

There are five errors in the code below. List five of them and:
identify the line by number,
state if the error is an interpreter (syntax) error or a runtime (logic) error, and
give a corrected version of the entire line.

1 var text = prompt('Enter a sentence');
2 var letter = prompt('Enter a letter to count');
3 var num = countLetters(text, letter);

4
5 document.writeIn('Found ' + num + ' ' + letter + 's');

.6

7 Function countLetters(alpha, phrase)
8 { var cnt = 0;
9 var i = 0;

10
11 while(i<=phrase.length)
12 { if(alpha == phrase[i]);
13 cnt++;
14 i++;
15 }
16 return cnt;
17 }

Explanation / Answer

line 7: funtion f is small (syntax error)

line 11:phrase.length will be replaced by alpha.length (run time error)

line 12:alpha will have index not phrase (syntax error)

line 12: no need of semocolon (run time error)

line13:end of curley braces of }  (run time error)

correct code is:

var text = prompt('Enter a sentence');

var letter = prompt('Enter a letter to count');

var num = countLetters(text, letter);

document.writeln('Found ' + num + ' ' + letter + 's');

function countLetters(alpha, phrase)

{ var cnt = 0;

var i = 0;

while(i <= alpha.length)

{

if(phrase == alpha[i])

{

cnt++;

}

i++;

}

return cnt;

}
