Passing a string to a function

To pass a string to a function in C++, you can follow these steps:

  1. Declare the function: Begin by declaring the function in the appropriate scope. The function should have a return type and a name, followed by parentheses that may or may not contain parameters.

  2. Define the function: Write the definition of the function, which includes the implementation or body of the function. This is where the actual code for the function resides.

  3. Add a parameter: Inside the parentheses of the function declaration or definition, specify a parameter of type string. This parameter will allow the function to accept a string as an argument when it is called.

  4. Call the function: To pass a string to the function, use the function name followed by parentheses. Inside the parentheses, provide the string as an argument. This can be a string literal, a variable of type string, or an expression that evaluates to a string.

  5. Process the string: Within the function definition, you can access and manipulate the passed string using the parameter name. You can perform various operations on the string, such as extracting substrings, modifying characters, or concatenating it with other strings.

  6. Return a value (optional): If the function is supposed to return a value, specify the return type in the function declaration and use the return statement within the function to return the desired value. If the function does not need to return a value, you can declare it as void.

By following these steps, you can successfully pass a string to a function in C++.
