ASCII code conversion: method
ASCII code conversion means moving between a character and its numeric code, or sometimes the reverse. The key is to be precise: each symbol has one matching code.
1) Identify what is being asked
- If you are given a character, find its ASCII number.
- If you are given a number, convert it back to the corresponding character.
2) Use the correct reference
Look up the ASCII table or the provided code list. Do not guess from the shape of the symbol; some characters are close together in appearance but have different codes.
3) Write the result clearly
- Character → code: write the number only if the exercise asks for the code.
- Code → character: write the exact symbol, letter, or digit.
If there are multiple steps in a longer problem, simplify the final answer to the requested form.
4) Check your answer
- Make sure the code matches only one character in the table.
- If you converted back, verify that the character you wrote gives the same code.
- For letters, check capitalization carefully, since uppercase and lowercase have different ASCII codes.
Quick tip
If the answer seems familiar, still verify it in the table. Small mistakes in ASCII conversion are usually caused by confusing similar characters or missing capitalization.
