What is the first step in creating a simple program to sum two numbers?

The initial step in creating a simple program to sum two numbers is to declare two integer variables. This is crucial because the variables are the means by which the program will store the values of the two numbers. By defining the correct data type, in this case, integers, the program ensures that it can handle the input numbers appropriately, allowing for accurate arithmetic operations.

Once the variables are declared, the program can then proceed to take input from the user and implement the summation logic. However, without the variables in place to hold this information, the subsequent steps wouldn't be meaningful or executable. Thus, starting with variable declaration establishes a solid foundation for the program's functionality. Following this step, the other processes such as taking user input, displaying the output, and potentially defining functions can occur.
