void function();

//Main Function
int main()

{
  //Variable Declaration
  long int n,n1,reverse=0;

  printf("Function Call");
  function();
  // Wait For Output Screen
  getch();

  //Main Function return Statement
  return 0;

How It Works

This C program demonstrates Simple Function. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
