hello, can you show me how to write the following code in c++? I want it to have a function and a main just like the one below

def convert_to_hex(hex): dictionary = {} dictionary[" "] = "0x20" dictionary["!"] = "0x21" # Can't Add in 22 since it is a Quotation Mark (") dictionary["#"] = "0x23" dictionary["$"] = "0x24" dictionary["%"] = "0x25" dictionary["&"] = "0x26" dictionary["'"] = "0x27" dictionary["("] = "0x28" dictionary[")"] = "0x29" dictionary["*"] = "0x2a" dictionary["+"] = "0x2b" dictionary[","] = "0x2c" dictionary["-"] = "0x2d" dictionary["."] = "0x2e" dictionary["/"] = "0x2f" dictionary["0"] = "0x30" dictionary["1"] = "0x31" dictionary["2"] = "0x32" dictionary["3"] = "0x33" dictionary["4"] = "0x34" dictionary["5"] = "0x35" dictionary["6"] = "0x36" dictionary["7"] = "0x37" dictionary["8"] = "0x38" dictionary["9"] = "0x39" dictionary[":"] = "0x3a" dictionary[";"] = "0x3b" dictionary["<"] = "0x3c" dictionary["="] = "0x3d" dictionary[">"] = "0x3e" dictionary["?"] = "0x3f" dictionary["@"] = "0x40" dictionary["A"] = "0x41" dictionary["B"] = "0x42" dictionary["C"] = "0x43" dictionary["D"] = "0x44" dictionary["E"] = "0x45" dictionary["F"] = "0x46" dictionary["G"] = "0x47" dictionary["H"] = "0x48" dictionary["I"] = "0x49" dictionary["J"] = "0x4a" dictionary["K"] = "0x4b" dictionary["L"] = "0x4c" dictionary["M"] = "0x4d" dictionary["N"] = "0x4e" dictionary["O"] = "0x4f" dictionary["P"] = "0x50" dictionary["Q"] = "0x51" dictionary["R"] = "0x52" dictionary["S"] = "0x53" dictionary["T"] = "0x54" dictionary["U"] = "0x55" dictionary["V"] = "0x56" dictionary["W"] = "0x57" dictionary["X"] = "0x58" dictionary["Y"] = "0x59" dictionary["Z"] = "0x5a" dictionary["["] = "0x5b" # Can't Add in 5c since it is a Backslash (\) dictionary["]"] = "0x5d" dictionary["^"] = "0x5e" dictionary["_"] = "0x5f" dictionary["`"] = "0x60" dictionary["a"] = "0x61" dictionary["b"] = "0x62" dictionary["c"] = "0x63" dictionary["d"] = "0x64" dictionary["e"] = "0x65" dictionary["f"] = "0x66" dictionary["g"] = "0x67" dictionary["h"] = "0x68" dictionary["i"] = "0x69" dictionary["j"] = "0x6a" dictionary["k"] = "0x6b" dictionary["l"] = "0x6c" dictionary["m"] = "0x6d" dictionary["n"] = "0x6e" dictionary["o"] = "0x6f" dictionary["p"] = "0x70" dictionary["q"] = "0x71" dictionary["r"] = "0x72" dictionary["s"] = "0x73" dictionary["t"] = "0x74" dictionary["u"] = "0x75" dictionary["v"] = "0x76" dictionary["w"] = "0x77" dictionary["x"] = "0x78" dictionary["y"] = "0x79" dictionary["z"] = "0x7a" dictionary["{"] = "0x7b" dictionary["|"] = "0x7c" dictionary["}"] = "0x7d" dictionary["~"] = "0x7e" hex_list = [] for letter in hex: if letter in dictionary: hex_list.append(dictionary[letter]) return hex_list def main(): hex = input('Please enter a string to be translated into hex: ') hex_list = convert_to_hex(hex) print(f'{hex} in hex is {hex_list}') main()
