C coding, not c++ nor java

Only C programming, please make sure all the examples run properly

You are tasked to write a program that will take in parameters from command line (agree) These parameters are a Word, Starting Position and the Number of Iterations. The program requires the index to move from the starting position (going right first) to the boundary and then going in reverse until the number of iterations have been met. The arguments are assumed to be in this order: word iterations Example 1, word = "Bouncy String". Start = 0, n = 15 Example 2, word = ''Some String'', start = 4, n = 15 Example 3, word = ''Some String'', start = 4, n = 0 s Example 4, word = "Bouncy String" start = -1, n = 15 Invalid start position Example 5, word = "Bouncy String". Start = 1, n = -1 Invalid iteration count Example 6, start = 1, n = -1 Invalid arguments length Invalid arguments are on a first seen basis. First argument that is invalid is the cause of the program terminating in the event of invalid arguments, the program should exit with code 1
