Premium CPU-Optimized Droplets are now available. strcmp () is a C library function that compares two strings lexicographically. Inside the function, we have created a while loop which will execute until the pointer a or b is not reached to a null character. This function starts comparing the first character of each string. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features.

We have declared two arrays of char type, i.e., str1 and str2. Run the sample and observe the order. printArray() will print array of 5 elements. C# This method is useful when the length of all strings is known and a particular memory footprint is desired. So, to avoid high space consumption in our program we can use an Array of Pointers in C. We cant directly change or assign the values to an array of strings in C. Here, arr[0] = GFG; // This will give an Error which says assignment to expression with an array type. The strcmp function compares the string s1 against s2, returning a value that has the same sign as the difference between the first differing pair of bytes (interpreted as unsigned char objects, then promoted to int ). Once the loop encounters a differing character in the strings, it would return the ASCII difference of the different characters and exit. These cookies track visitors across websites and collect information to provide customized ads. A single Relational operator is unique to a certain operation, while compare() can perform lots of different operations alone, based on the type of arguments passed. The strcmp () function accepts two char pointers (strings) as arguments, and returns 0, if both the strings are equal. Approach 1: Using the functions strcmp () from string.h. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. Unlike numpy.equal, this comparison is performed by first stripping whitespace characters from the end of the string.

I have filled up these two arrays with names and now I must compare for example, the first element of arrs and the third element of arrj. In case they are not equal, we can also analyze and find out which string is lexicographically (lexicographic order means dictionary order, that is, the words which start from 'a' come before the words that start with 'b' and the earlier is lexicographically smaller than the later, we'll see about this later in the article) larger than the other by the various methods of string comparison in C.
