Editorial Staff - - C Programming Tutorial
In this program, we are going to share a C program to segregate even and odd elements of array. 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 segregate even and odd elements of array 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.
