Why are physically impossible and logically impossible concepts considered separate in terms of probability? Please follow the steps below to create flowcharts: Firstly, create the schema for creating the diagram. If the number is less than zero, the program prints "Less than 0". all systems operational. The second symbol is an Input/Output (I/O) symbol that is labeled specifically to show that this step is to read input data. The fourth symbol is again a processing symbol. Instead, describe the problem and what has been done so far to solve it.

The IFTHEN structure says that if the condition is true, then perform process 1; and if it is not true, then skip over process 1. The next steps will be to organize some of our nodes into logical groupings, and then link each of the nodes with edges. However, if you do not want to choose between the two processes, and you simply want to decide if a process is to be performed or not, then use IFTHEN structure only. In real-life applications, sometimes, you will need to change the sequence of execution according to conditions.
