What is a function?

A function is a reusable sequence of statements designed to do a particular job.

What function is run first of all in a C++ program?

a function named main

What are return values?

The specific value returned from a function is called the return value.

Are nested functions allowed in C++?

Nested functions are not supported

Unlike some other programming languages, in C++, functions cannot be defined inside other functions.

1.A function is a reusable sequence of statements designed to do a particular job.
2. main().
3. A function can optionally return a value as output. Functions are useful for encapsulating common operations in a single reusable block, ideally with a name that clearly describes what the function does.
4.No, you can execute another function inside the main function but you have to call it , not declare it. The declaration of the called function must be outside the main function.

  1. What is a function?
  • A function is a block of code that performs a specific task and can be reused.
  1. What function is run first of all in a C++ program?
  • The function called “main()”.
  1. What are return values?
  • Return values are the values that are returned by a function to the calling function. If the function is declared of the “void” type, there is no value returned.
  1. Are nested functions allowed in C++?
  • Nested functions (defining another function within a function) is not allowed. However, a function can be called by a function which can itself call a function, etc.

Hi everybody,
Can someone please explain to me this:
How to write this code without using “using namespace”:
#include
#include

using namespace;
string FunctionName (string text){
return “Hi” + text;
}

int main () {
cout << FuntionName (Sport);
return 0;

Also should I use using namespace or not. I found somewhere that c++ community recommended to not use it,
Thank you

Namespaces are a way of separating different parts of code, but are not necessary, at least not for small applications. For the most part you don’t need them.

As for your code example, I’m not entirely sure what you intend to do? include don’t include anything and namespace is not named, it should be using namespace NamespaceName.

Have you tried removing the namespace line and see if your solution still works?

#318

Sorry- should be namespace std;

#319

Ahh, yes using functions in the std namespace requires either using namespace std or explicitly calling the function with a prefix std::functionName.

So if you want to call cout without the std namespace, you will have to call the function using std::cout.

Thank you,
This works:
#include

using namespace std;

string Greetings(string name){

return name;

}
int main()
{
string name = “”;
cin >> name;
cout <<name << " is my name, sir";

return 0;

}
But how to do it without “using spacename std:”?

#321

Replace cin and cout with std::cin and std::cout.

  1. Reusable code that executes particular commands in particular order considering particular conditions. Functions may or may NOT take input or generate output (but usually they do).
  2. The main() function.
  3. This is the output of a function which can be used or stored in variable after the function is processed.
  4. No.
