In this C program, you will take command-line arguments of 10 numbers, which are assumed to be integers, and find the median or the average of them. The average of the array should be a floating point number (double). Before the numbers on the command line, there will be an argument that indicates whether to find the median (- m) or average (-a), if the user entered an invalid option or incorrect number of arguments, the program should display an error message. To find the median of an array, use the selection_sort function provided above to sort the array, the median is the number that is halfway into the array: a[n/2], where n is the number of the elements in array a.

input and output:

./a.out a 2 6 8 4 9 10 7 3 11 5

output: 6.5

./a.out m 2 6 8 4 9 10 7 3 11 5

output: 7

./a.out

output: usage: ./a.out option (a or m) followed by 10 numbers

./a.out d 2 6 8 4 9 10 7 3 11 5

output: Invalid option

1) Name the program command_line.c

2) Use strcmp function to process the first command line argument.

3) Use atoi function in to convert a string to integer form.
