Answer / kms

The following code compares the strings alphabetically:

For example:

1. "bite" is greater than "apple" even though length of bite
is less than apple. ( it is greater lexicographically)

2. "It is good" is lower than "It is great".

Answer / sujith

#include<stdio.h>
int str_cmp(const char *s1, const char *s2)
{
unsigned int i = 0, diff;
while(*(s1+i) && *(s2+i))
{
diff = (*(s1+i)-*(s2+i));
if(!diff)i++;
else break;
}
return diff;
}
int main()
{
printf("chuma %d ", str_cmp("abcd","abcde"));
return 0;
}
U can use this as a prototype and enhance this. I havent
even tried compilng this.

Answer / fionaa

corrected:

Returns an integral value indicating the relationship
between the strings:
A zero value indicates that both strings are equal.
A value greater than zero indicates that the first character
that does not match has a greater value in str1 than in
str2; And a value less than zero indicates the opposite.

int compare(char str1[], char str2[]) {
int flag = -1;
int i=0;
while(str1[i]!='\0' && str2[i]!='\0'){
if((str1[i]==str2[i])) {flag = 0;}
else if (str1[i]>str2[i]) {
flag=1;
break;
}else if(str1[i]<str2[i]){
flag = -1;
break;
}
i++;
}

if(strlen(str1)==strlen(str2) && flag==0 ){
flag = 0;
}
else if(strlen(str1)>strlen(str2) && flag==0 ){
flag = 1;
}
else if(strlen(str1)<strlen(str2) && flag==0 ){flag = -1;}
return flag;

15 Answers   Microsoft, Sony,

write an interactive C program that will encode or decode a line of text.To encode a line of text,proceed as follows. 1.convert each character,including blank spaces,to its ASCII equivalent. 2.Generate a positive random integer.add this integer to the ASCII equivalent of each character.The same random integer will be used for the entire line of text. 3.Suppose that N1 represents the lowest permissible value in the ASCII code,and N2 represents the highest permissible value.If the number obtained in step 2 above(i.e.,the original ASCII equivalent plus the random integer)exceeds N2,then subtract the largest possible multiple of N2 from this number,and add the remainder to N1.Hence the encoded number will always fall between N1 and N2,and will therefore always represent some ASCII character. 4.Dislay the characters that correspond to the encoded ASCII values.  The procedure is reversed when decoding a line of text.Be certain,however,that the same random number is used in decodingas was used in encoding.
