Can we have more than one function in C?

We could write multiple functions. The main problem is the trouble of calling more than one functions since we need to return multiple values and of course, having more number of lines of code to be typed.

How do I run two functions simultaneously in CPP?

Here’s a C++/OpenMP program which calls function_a and function_b as simultaneously as your hardware will let you:

1. #include
2. using namespace std;
3. void function_a ( void ) { for ( int i=0; i<1000; i++ ) cout << “A”; }
4. void function_b ( void ) { for ( int i=0; i<1000; i++ ) cout << “B”; }
5. int.

How do you call two functions at the same time in python?

Use threading. Thread. start() to run multiple functions at the same time

1. def a():
2. print(“Function a is running at time: ” + str(int(time. time())) + ” seconds.”)
3. def b():
4. print(“Function b is running at time: ” + str(int(time. time())) + ” seconds.”)
5. threading. Thread(target=a). start()
6. threading. Thread(target=b).

Can you have 2 main functions?

You can have two functions called main . The name is not special in any way and it’s not reserved. What’s special is the function, and it happens to have that name. The function is global.

What are threads in C++?

A thread of execution is a sequence of instructions that can be executed concurrently with other such sequences in multithreading environments, while sharing a same address space. An initialized thread object represents an active thread of execution; Such a thread object is joinable, and has a unique thread id.

How do you declare a thread in C++?

To start a thread we simply need to create a new thread object and pass the executing code to be called (i.e, a callable object) into the constructor of the object. Once the object is created a new thread is launched which will execute the code specified in callable.

How do you call a function in multithreading?

To run a custom function with parameters, you need to create an object of the Thread class from the threading module. In the class constructor, you need to pass the function name you want to execute in a thread to the “target” parameter. The arguments are passed in the form of a tuple to the “args” parameter.

How many functions can be used in C program?

3) There is no limit on number of functions; A C program can have any number of functions. 4) A function can call itself and it is known as “Recursion“.

Can I have multiple Main () methods in the same class?

Yes, you can have as many main methods as you like. You can have main methods with different signatures from main(String[]) which is called overloading, and the JVM will ignore those main methods. You can have one public static void main(String[] args) method in each class. Those two methods have the same signature.
