    Find the length of the char array(strlen(var)) or string(var.length()), and only copy length-1 characters to your new variable. If your new variable is a char array, be sure to create one extra index position and set the last character equal to '\0'. There are some functions, like atof(), that will convert char arrays to numeric types, if that is your ultimate goal.

    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
