To compile this program in Linux:

1. Save this file with extension .c
2. g++ compiler come pre installed in linux. Type this in terminal g++ alternate.c -o alternate. Here, I have assumed that the file name is alternate.c. -o array will provide me with an output file with extension exe file and name alternate.
3. Now, run this file typing ./alternate and press enter.

To compile this program using cmd:

1. Save this file with extension.c
2. Type this in the cmd g++ alternate.c -o alternate.
3. To run type alternate and press enter.

Note: To use g++ compiler in windows user has to install these compiler by itself as g++ compiler does not come per installed in windows operating system.
