Finally, it displays the concatenated string. In C Programming, we learned about the String Concatenation method with and without the usage of strcat function with the examples and how to make use of it.

I hope the Concatenation of string with various methods would help out you with those examples. This is a guide to String Concatenation in C. Here we discuss the syntax, working, and methods of String Concatenation in C along with the examples and code implementation. You may also look at the following articles to learn more —.

When the execution of the loop is completed, then the value of ' i ' becomes equal to the length of the string plus one.

We will define another new loop, which is basically used to concatenate the two strings. In this way, both the strings are combined together to form a single string. We take the two strings as user input and store them in the variables string1 and string2, We declare two char pointers str1 and str2.

The str1 contains the address of string1, and str2 contains the address of string2. We create a loop which iterates until the null character of string1 is encountered.

When the execution of the loop is completed, then the pointer str1 points to the location that exists just after the location of the last character. We define another while loop that iterates till the null character of string2 is encountered.
