It doesn't have an integer value to convert to. What it DOES have is a string of characters that can be represented as both a number and a letter. Maybe you wanted this? MyString[x] Where x is the character you want to get.
well you can convert it into an integer with the help of the function strlen() ,witch is found in the string.h library.the function returns the number of characters that the string is composed of.for example "hello world" the function will return the value 11. any character is evaluated,even space.
that is all y can think of.hope it helps.
