Sep 21, 2007  strcmp compares correspoding characters until there is a mismatch and one of the values is not a null terminator. If one is a null terminator, then if the other is also, the strings are equal. Otherwise, the difference between the first argument less the second argument is returned.

The function strcmp() is a built-in library function and it is declared in “string.h” header file. This function is used to compare the string arguments. It compares strings lexicographically which means it compares both the strings character by character. It starts comparing the very first character of strings until the characters of both strings are equal or NULL character is found.

If the first character of both strings are equal, it checks second character and so on. This process will be continued until NULL character is found or both characters are unequal.

Here is the syntax of strcmp() in C language,

This function returns the following three different values based on the comparison.

1.Zero(0) − It returns zero if both strings are identical. All characters are same in both strings.

2. Greater than zero(>0) − It returns a value greater than zero when the matching character of left string has greater ASCII value than the character of the right string.

3. Less than zero(<0) − It returns a value less than zero when the matching character of left string has lesser ASCII value than the character of the right string.

C Strcmp Usage

Here, we have to create a strcmp (string compare) function that compares two string but ignores cases of the characters of the string. The function will return -1 if string1 < string2, 0 if string1 = string2, 1 if string1 > string2. Auto tune apps with video.

Let’s take an example to understand the problem,

Strcmp Code In Dev C++

To create our own strcmp function that ignores cases while comparing the strings. We will iterate through all characters of both the strings, if characters at ith index are the same i.e. string1[i] string2[i], continue. If string1[i] > string2[i], return 1. If string1[i] < string2[i], return -1. If the string ends returns 0.

Here, we have to ignore cases, so A and a will be considered the same. We will use the ASCII values of the characters, then ASCII for a = 97 will be equal to ASCII of A = 65.
