Would you like to learn basic ascii? Yes, keep reading.
The common ascii table has 95 characters, just the numbers and letters are 62 characters, the other symbols are the remaining 33.
We are going to learn this with their respective hecadecimal code, it is easier to learn and convert to decimal and binary.
The easiest way to convert hex to dec is by knowing the multiples of 16 wich are: 16,32,48,64,80,96,112. Thats all we need.
Convert 25 to dec: you multiply the first digit with 16 and add the second digit, 2x16: 32, and then 32+5: 37, that’s our answer.
Convert 25 to bin: if you can count in binary then you convert each digit: 0010 and 0101, but you put them together: 00100101.
Now, to convert from dec to hex, you have to find the multiple of 16 below the given number, and then the difference.
Convert from dec to hex: 84, ok 16x5: 80, our first digit is 5, then 84-80: 4, our last digit is 4, our answer is 54.
Convert 50 to hex: 16x3 is 48, first digit of our answer is 3, 50-48: 2, our answer is 32
So, let’s begin with the numbers: they are all the same, you just put a 3 before the wished number, here is a table.
also, we have to know that a “space” between words or numbers is 20 ( always in hex )
Decipher this to continue with the letters, don’t use a convert.
51 32 49 52 49 53 57 50 54 53 52.
P.D: this numbers are in dec, convert them to hex and find their value. Remember that a 20 in hex, or 32 in dec means a space. ( just a space, no character at all )
