August 29, 2012 - Following is the syntax of the C library strcmp() function − ... Zero, if the string are equal. Negative, if the first string is less than second string lexicographically. Positive, if the first string is greater than second string lexicographically. In this example, we demonstrate the usage of string characters comparison using strcmp() function.

At the first mismatch, if the ASCII value of the character in the second string is greater then the function returns a negative number. The strcmp() function is defined in the <string.h> header file.

April 17, 2024 - Greater than zero (>0): The return value is greater than zero if the ASCII value of the first unmatched character in the left-hand string (string1) is greater than that of the corresponding character in the right-hand string (string2). The result is the difference between the ASCII values of the first unmatched characters, i.e., string1 - string2. Example: strcmp in C

Upon completion, strcmp() shall return an integer greater than, equal to, or less than 0, if the string pointed to by s1 is greater than, equal to, or less than the string pointed to by s2, respectively. No errors are defined. The following sections are informative. The following example compares the information read from standard input to the value of the name of the user entry.

strcmp in C | String Comparison Function with Examples
February 5, 2025 - Example: For the comparison between "apple" and "orange", the first mismatch is found between 'a' (ASCII 97) and 'o' (ASCII 111). strcmp() calculates the difference (97 - 111) and returns -14.

Uhm.. way too complicated. Go for this one:
int strCmp(const char* s1, const char* s2)
{
while(*s1 && (*s1 == *s2))
{
s1++;
s2++;
}
return *(const unsigned char*)s1 - *(const unsigned char*)s2;
}
It returns <0, 0 or >0 as expected
You can't do it without pointers. In C, indexing an array is using pointers.
Maybe you want to avoid using the * operator? :-)

First of all standard C function strcmp compares elements of strings as having type unsigned char.
Secondly the parameters should be pointers to constant strings to provide the comparison also for constant strings.
The function can be written the following way
int strCmp( const char *s1, const char *s2 )
{
const unsigned char *p1 = ( const unsigned char * )s1;
const unsigned char *p2 = ( const unsigned char * )s2;
while ( *p1 && *p1 == *p2 ) ++p1, ++p2;
return ( *p1 > *p2 ) - ( *p2 > *p1 );
}

strcmp() Function in C
January 9, 2024 - Next, we compared the strings using the strcmp Function in C and stored the value in the variable named ans. Then on the basis of the value stored in the “ans” variable, we printed the Statements on the screen. Since we have initialized both of them with the same value, we get the expected result as “Strings as equal” on the output screen. Example 2 of strcmp Function in C This code takes a lexicographically greater string as the first argument.
