What is Kevin in ASCII values?

Answer 1

Determining the ASCII values for any string of characters is simple, requiring a for loop and an understanding of strings.

All a string is in C is an array of characters terminated with ASCII 0 (also known as a zero-terminated string or NUL-terminated string). The following block of code assumes that "sz" is a pointer to your string data and "psz" is a character pointer:

for (psz=sz; *psz; psz++) printf("%02X:%03d ", *psz);

printf("\n");

Step by step, what this code does is:

- Initializes "psz" to the same value as "sz", which means they both point to the address of the first character in the string;

- Checks if the character at the address in "psz" is not zero (meaning not at the end of the string) and, if so, breaks out of the loop;

- Displays a two-character hexadecimal (base 16) and a three-digit (base 10) ASCII representation of the character followed by a space;

- Loops back to the character check

- Displays a newline to move the cursor to the beginning of the next line.

Before the code, and inside your desired function block, define "psz" and "sz" as char* types, and set "sz" to the string "Kevin".

The full listing is as follows:

int main()

{

char *psz, *sz="Kevin";

for (psz=sz; *psz; psz++) printf("%02X:%03d ", *psz);

printf("\n");

return 0;

}

Note that if you're using C++ you'll need to change "char" to "const char".
