four-input gates

Build a combinational circuit with four inputs, in[3:0].

There are 3 outputs:

out_and: output of a 4-input AND gate.
out_or: output of a 4-input OR gate.
out_xor: output of a 4-input XOR gate.
To review the AND, OR, and XOR operators, see andgate, norgate, and xnorgate.

module top_module( 
    input [3:0] in,
    output out_and,
    output out_or,
    output out_xor
);
    assign out_and=in[0]&in[1]&in[2]&in[3];
    assign out_or=in[0]|in[1]|in[2]|in[3];
    assign out_xor=in[0]^in[1]^in[2]^in[3];
