Comparing Strings

Diane- · Jun 11, 2003, 00:01

Guys i have a question about comparing strings.For example

string word1;
string word2;

word1="Tremendous";
word2="Tremble";

word1<word2;

The boolean value will be false , cause computer compares each character one by one and as "b" has lesser value in ASCII than "e", it gives a false value.
So the question is , can computer stop at the first character in the string, meaning that it will compare just "T" and set the boolean value to true?

1. the value 'b' is less than the value 'e'

but you are true, word1 < word2 is false.

2. If computer stops after the first symbol the result will be false , because 'T' < 'T' is false ('T' <= 'T' is true).

Agregat yes u right , thats what i wanted to write, but somehow managed to write in the wrong way.
And I know that "T"<"T" will be false, thats not what i was asking.
Nam nichego ne nujno ,nujen bil otvet na etot vopros, vozmojno li ostanovit posle pervoi bukvi.
Danyer ,"dobavit proverochki" kak na angliyskom budet zvuchat?

Eto ne svyazano s kakim to imenno projectom i ya znayu chto etot privedennii mnoyu primer veren. vopros lij v tom, mojli li ostanovit computer posle pervoi bukvi, v lubom sravnenii string-ov.
Neznayu kak vam eshe obyasnit

mojno.

1. proveryai TOL'KO pervuiu bukvu (if(s1[0]==s2[0]))

2. s[i]

i nachinai s 0

ne narashivai.

chto to je samoe chto i s1[0]

----------

add a condition checking
e.g.
if ( strlen(s1) > strlen(s2)) i t.d. biblioteka string.h
