strcmpi() function in C is same as strcmp() function. But, strcmpi() function is not case sensitive
. i.e, "P" and "p" are treated as same characters. Where as, strcmp() function treats "S" and "s" as different characters. .
strcmpi() is a library function of string.h header file, if strings are same (in any case Upper/Lower) it will return 0 otherwise it will return the difference of first dissimilar characters (i.e. non zero value).
For Example: - we have two strings "Hello World!" and "HELLO WORLD!", strcmp() function will return 0 becuase strings are same.
int strcmpi ( const char * strng1, const char * strng2 );
Enter string1: Hello World! Enter string2: HELLO WORLD! Both strings are same.

Functions | Description |
---|---|
strcat( ) | The strcat() function is used to concatenate one string(source) at the end of another string(destination). |
strncat( ) | Appends first n characters of a string at the end of another. |
strcpy( ) | Copies from str2 into str1 |
strncpy( ) | Copies given number of characters of one string to another |
strlen( ) | Gives the length of str1 |
strcmp( ) | Returns 0 if str1 is same as str2. Returns <0 if strl < str2. Returns >0 if str1 > str2 |
strcmpi( ) | Same as strcmp() function. But, this function negotiates case. “A” and “a” are treated as same. |
strchr( ) | Returns pointer to first occurrence of char in str1 |
strrchr( ) | last occurrence of given character in a string is found. |
strstr( ) | Returns pointer to first occurrence of str2 in str1 |
strrstr( ) | Returns pointer to last occurrence of str2 in str1 |
strdup( ) | Duplicates the string |
strlwr( ) | Converts string to lowercase |
strupr( ) | Converts string to uppercase |
strrev( ) | Reverses the given string |
strset( ) | Sets all character in a string to given character |
strnset( ) | It sets the portion of characters in a string to given character |
strtok( ) | Tokenizing given string using delimiter |
