Hello @Hk199977,

ASCII: Short for American Standard Code for Information Inter-exchange, ASCII is a standard that assigns letters, numbers, and other characters in the 256 slots available in the 8-bit code. The ASCII decimal (Dec) number is created from binary, which is the language of all computers. As shown in the table below, the lowercase “h” character (Char) has a decimal value of 104, which is “01101000” in binary.

As you know, the size of char is 8-bits(or 1 byte).
So, we can represent 256 different characters using these 8 bits.
ASCII has assigned a separate decimal number to each of these 256 characters to uniquely represent/identify them in memory.

Common:
digits: 58-67
capital alphabets: 65-90
lower alphabets: 97-122

NOTES:

  1. char c=‘9’;
    int n;
    n=c; //This will store it’s corresponding ASCII number i.e. 67.

    If you wants to store 9 instead of it’s ASCII number.
    n=c-‘0’;
    Reason:
    67-58=9.

  2. if you want to convert smaller alphabet to capital then subtract 32 from it.
    Example:
    char c1=‘a’;
    char c2;
    c2=c1-32;

    For reverse, add 32.
    Reason:
    lower alphabets differ by 32 positions from their corresponding capital alphabets.

Hope, this would help.
Give a like if you are satisfied.
