In this program, we are going to share a C program to concatenate two strings lexically. If you are a beginner and want to start learning the C programming, then keep your close attention in this tutorial as I am going to share a C program to concatenate two strings lexically with the output.
We have designed this program for beginners for learning purpose. Copy below c program and execute it with c compiler to see the output of the program.

Enter a string : hello this
Enter another string to concat : is freewebmentor
hello is freewebmentor this
