Write a program that accepts as command line arguments the sign of a math operation (+, -, x, or /) and two integer numbers and displays the result of the operation (all integer operations). For example, if the arguments are +, 5, -3, the program should display 2. You may find strcmp function useful. Note: x for the multiplication is letter x, not *. (* has special meaning to Unix shell.)

Sample run: ./a.out - 5 2 output: 3

1) Name your program command_math.c.

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