Thread: so I need help in endng the loop from the input of the user before & after the loop

Code:

Do you have a specific question or problem?

You really really need to consistently use some indentation style. The way your program is presently presented it is very hard to read, and almost impossible to follow your logic.


Jim

A problem. In other words... how do I properly write a sentinel loop?

Where do you want this loop? You already have several loops with sentinel values, is there something wrong with them?

Jim

Want it to come right after the 1st print function each time it loops
