There's no such think in the C language.

basically "char" is what C calls a byte, often C treats chars as signed so
they commonly range from -128 to +127 but otherwise they are basically the
same the bytes you see in other languages, debuggers, hex dumps etc....

so the 157 byte in C wouild look like a char with a value of -99

Strlen just measures the distance from the start of the string to the end of
the string.  it'll help you determine how much spoace the data in the string
is ocupying.

in C strings can't contain character 0 as that value is reserved to
indicate the end of the string
