lowercase

I'm running Rails 2.3.2. How do I convert "Cool" to "cool" ? I know "Cool".downcase works, but is there a Ruby/Rails method that does the opposite of capitalize , i.e., uncapitalize or decapitalize ? There is no inverse of capitalize , but you can feel free to roll your own: class String def uncapitalize self[0, 1].downcase + self[1..-1] end end tfischbach There is also: "coolat_cat".camelize(:lower) # => "coolCat" You could also do this with a simple sub : "Cool".sub(/^[A-Z]/) {|f| f.downcase } str = "Directly to the south" str[0] = str[0].downcase puts str #=> "directly to the south" There

The .toLowerCase method is giving me an error when I try to use it on numbers. This is what I have: var ans = 334; var temp = ans.toLowerCase(); alert(temp); And then it gives me this error: 'undefined' is not a function (evaluating 'ans.toLowerCase()') I don't know where I got this wrong. I always thought that numbers can also be parsed, with no change in result (maybe that's where I stuffed up).

I am reading content from a file to be read into a char array in C. How could I change all the letters in the file that are lowercase to uppercase letters? Here's a possible algorithm: Open a file (let's call it A) - fopen() Open another file to write (let's call it B) - fopen() Read the content of A - getc() or fread(); whatever you feel free Make the content you read uppercase - toupper() Write the result of the 4-step to B - fwrite() or fputc() or fprintf() Close all file handles - fclose() The following is the code written in C: #include <stdio.h> #include <ctype.h> #define INPUT_FILE

I need to make a function that reads a string input and converts the odd indexed characters in the string to upperCase and the even ones to lowerCase. function alternativeCase(string){ for(var i = 0; i < string.length; i++){ if (i % 2 != 0) { string[i].toUpperCase(); } else { string[i].toLowerCase(); } } return string; } How to fix my code? Try this: function alternativeCase(string){ var output = ""; for(var i = 0; i < string.length; i++){ if (i % 2 != 0) { output += string[i].toUpperCase(); } else { output += string[i].toLowerCase(); } } return output; } function alternativeCase(string){
