C++ Programming question: Double Nested While Loop?

Question

What is the basic format for a double nested while loop? How different is it from just a while loop?

Answer 1

simple while loop:

While(condition)

{ statements;

}



Double nested while loop:

While(condition1)

{ statement1;

While(condition2)

{ statement2;

}

}



In nested while loop to reach statement2 both condition 1 and 2 should be fulfilled where as in single while loop there is only one condition to reach statements.

Answer 3

Nested While Loops

Answer 4

First off, your data validation isn't completely correct. What if someone enters a decimal or character? They could enter 2.5 for the years, or the letter J for amount of rainfall and it would still run! Also, remove the semi-colon from the end of this line for ( int month = 1; month <= numMonths; month++ ); That should clear up all your errors. The semi-colon was ending the loop immediately. Because the loop finished there, the variable month was no longer valid for your cout statement, causing the error.
