Apr 2, 2025 · In C, strcmp() is a built-in library function used to compare two strings lexicographically. It takes two strings (array of characters) as arguments, compares these two strings lexicographically, and then returns some value as a result.

Whenever you are trying to compare the strings, compare them with respect to each character. For this you can use built in string function called strcmp(input1,input2); and you should use the header file called #include<string.h>

9.1 Defining the Comparison Function. In order to use the sorted array library functions, you have to describe how to compare the elements of the array. To do this, you supply a comparison function to compare two elements of the array. The library will call this function, passing as arguments pointers to two array elements to be compared.

Aug 16, 2011 · Here is the complete source code that has own functions find_length (like strlen) to find the length, join_strings ( like strcat) for joining strings, compare_strings (like strcmp) for comparing two strings and copy_string (like strcpy) to copy one string from another.
