The free versions are simply the compiler/IDE, however.

codepad:- This compiler is mostly used in interviews because it allows you to connect with other people.

It allows you to create an account and save your projects. onlinegdb:- It is simple, and has a better debugger for C and C++ than you’d find on a terminal.Ideone:- This is a very simple compiler for small projects.These are some top websites to run C program online. Taking input from the user is very common in programming but many times using online compilers we can’t take input from the user. But online compilers have some limitations. There are several sites that allow us to run C programming online. These compilers and text editors may differ from system to system. Printf('%s ', lane) //validate user inputThere are numerous compilers and text editors we can use to compile and execute the C program. Getchar() //To capture the new line character. Printf('%s ', Light) //validate user input To capture the SPACE or ENTER since they are taken as characters. If you want that to be able to happen, you could use getchar() %s on the other hand takes the whole answer and thus the whole of it is printed out.Īnother problem could have been pressing the SPACE key or ENTER key after giving the answer. In your case, if the user had put YES for the first question, only Y would appear in the printf and not YES.

This is because %c will only accept one character and not a string like %s would. I hope you understand why %s worked and not %c. Printf('%c', Light) //validate user input USER_INPUT Light Red?, Lane Right? Turn Yes? Is there a rule about the use of multiple scanf's? Here's a screen shot:įile:///C:/DOCUME%7E1/smr10/LOCALS%7E1/Temp/moz-screenshot.jpgfile:///C:/DOCUME%7E1/smr10/LOCALS%7E1/Temp/moz-screenshot-1.jpg #include Then it asks the second question, but does not allow the user to answer the question and moves on to the last question which it does allow user input. When I run the program it asks the first question and then outputs the answer. I want to ask 3 questions and then gather userinput into char variables. I'm having a problem with this code below.
