simple but crucial !!!!!

None

in a strcmp statement if the 2 strings are equal is it the condition of true or false i.e 1 or 0,i always get confused with this,wanna get cleared atleast now.

if(strcmp(str1,str2)>0)---------> wat does dis >0 imply?

c in both strings u r traversing from left to rite
let elements of str1 be a_i and tht of str2 be b_i
now for each i it goes on checkin which is greater...for the 1st such i found it returns>0 if a_i>b_iand <0 for a_i<b_{i

eg computer(str1) n commander(str2)
now a0=b0,a1=b1,a2=b2 buta3>b3
hence returns >0 for strcmp(str1,str2)

but if u had given strcmp(str2,str1)
the same eg as above will return <0 as the second string(str1) is greater in terms of the idea ive expressed above}

It means that the first string is greater than the second
i.e it lies earlier in the dictionary
