You can find the ASCII value of numbers greater than 9 using the following functions: std::to_string or boost::lexical_cast or std::ostringstream depending on the compiler that you are using.

Numbers don't have ASCII values. Only characters do. To find the ASCII bytes
for 255 characters and controls, do a web search for "ASCII codes".
If you can't find them on your keyboard, use charmap.exe () ASCII 28H and 29H [] ASCII 5BH and 5DH {} ASCII 7BH and 7DH
You compare it against the known character ranges! The following is an example to identify ASCII characters:First, check if it is ASCII. All ASCII characters are less than 0x80. If it is:Check for a printable character (range: 0x20 to 0x7E). If it is:0x20: Space0x30 to 0x39: Numbers0x41 to 0x5A: Capital letters0x61 to 0x7A: Lowercase lettersEverything else are special symbols ($, #, !, ?, and friends).Everything else are control charactersIf the value is >= 0x80, then it is not ASCII. What character it represents is specified by the codepage.Note that some codepages (most notably the Windows-1252 codepage, sometimes incorrectly called ANSI) are extensions to the ASCII standard, so the characters less than 0x80 would be the same as in ASCII.
"in order to check the repetition of characters in a string in c" we have to pick up each element of the string using a for loop and then using its ASCII value check whether another character of the same ASCII value exists using an if condition statement.
Store the numbers in a suitable container such as an array. Assume the first number is the smallest and assign its value to a local variable. Traverse the remainder of the sequence, comparing each element's value to the stored value. If an element has a lower value, assign its value to the local variable. When the sequence is fully traversed, the local variable will hold the value of the smallest value in the sequence. Return that value.
Write a simple program to find out how many of the numbers from 1 to 10 is greater than 4.
