Infinite loop with cin when typing string while a number is expected

Question

In the following loop, if we type characters as the cin input instead of numbers which are expected, then it goes into infinite loop. Could anyone please explai

Answer 1

Perhaps, it's because,

1. cin is a streaming function. When a non-numeric is entered instead of numbers, it is ignored. And you are prompted for re-entry.
2. Even if you did give numeric inputs, you will be prompted for more inputs since you're on an infinite loop.

You can solve this problem like this: 1. Create a function to take in a string input. 2. return it as numeric after conversion. Use strtod() for conversion.

Hope this helps :)
