Solved The Problem With Using Fgets After Scanf Coding Ninjas This article discusses a common problem of how the function fgets doesn’t work after scanf and then derives the solutions to it. Output x = 10, str = explanation: the problem with the above code is scanf () reads an integer and leaves a newline character in the buffer. so fgets () only reads newline and the string "test" is ignored by the program.
Github Aditya4436 Coding Ninjas Solved Problems For example in your code, loops is a local un initialized variable, containing garbage. if scanf fails to fill the desired value, following while loop may run arbitrarily. Solved: the problem with using fgets () after scanf () introduction the scanf () function is a widely used function in c c . although the syntax to use it is simple, it is important to understand some areas where its usage would require careful handling. one such area is when fgets () is posted by sahil saini july 27, 2021 codestudio python. The scanf () function is a common c c function. even though the syntax is basic, it is vital to recognise several circumstances wherein its use would necessitate caution. one example is when fgets () is called after scanf (). in this post, we'll look at why fgets () doesn't work after scanf (), as well as possible fixes. While using the scanf () function, a very common problem is faced if it is used before an fgets () part. because of this issue, the fgets () function does not read some office of the input as the scanf () part leaves a newline graphic symbol in the buffer.

Reading using fgets works a bit different, it stops reading at the newline, but unlike scanf, it considers this newline character to be input as well and it will put the trailing newline into the char array you are reading to, which may or may not be a problem, definitely something to consider. Learn about the issues faced when using scanf after fgets or gets in c programming. understand how to resolve common problems and improve your coding practices.
