Arithmetic Dispatch Table of Function Pointers

The four operations and their names are already written for you. Build a dispatch table

int (*ops[4])(int, int) = { add, sub, mul, max_of };

and use it to run the commands from input.

Input: the first line is commands, the number of commands that follow. Each command is three integers on its own line: an operation code (0 = add, 1 = sub, 2 = mul, 3 = max) and the two operands a and b.

For each command print one line in exactly this form:

name(a, b) = result

using the matching entry of the names array.

For the input:

3
0 6 3
2 4 5
3 9 -2

the output is exactly what is shown in Expected Output.

Each line ends with a newline. Do not use if/else or switch to pick the operation — index the table.
