Answer:
This is normal as all processes need at least one input and at least one output
Step-by-step explanation:
In a process, it is only necessary to have at least one input and one output. However, it is possible to have multiple inputs and a single output, or even have a single input and multiple outputs. Here is an example of a process with two inputs and a single output in c ++. Which is simply a sum:
#include <iostream>
int main()
{
 // Variables.
 int NumberA;
 int NumberB;
 int Sum;
 
 //Requesting numbers.
 std::cout<<"Introduce the first integer:\\"; std::cin>>NumberA;
 std::cout<<"Introduce the second integer:\\"; std::cin>>NumberB;
 //Sum
 Sum=NumberA+NumberB;
 std::cout<<"The sum is:"<<Sum<<::std::endl;
 
 return 0;
}
