Since you have posted this question in .NET Training category, let me answer you in the .NET programming language. You have several String manipulation functions provided by the .NET framework. For this particular scenario, String.Replace is the best method which accepts 2 parameters, and has the following syntax: string.Replace("string_to_search","string_to_replace") Let's see an example below: string abc = "All the lazy foxes jump over the lazy dogs." Now in this string let's replace the word "the" with "my" So the piece of code is a single line as listed below to achieve our requirement. string manipulatedString = abc.Replace("the","my"); Now the manipulatedString contains, the following text: "All my lazy foxes jump over my lazy dogs." Please not here that the replace method accepts 2 parameters and returns a string. This is the signature of the Replace method.
