How to decipher text in c2/9/2023 ![]() %s by itself in scanf is always a bug and may be a security vulnerability. You should also be specifying how much space is available for each string in the format specifier. To understand this example, you should have the knowledge of the following C programming topics. In this example, you will learn to print the first line from a file in C programming. it's not clear from this fragment whether you're not already doing so, but you have to either define space to store the entire dataset, or do all your processing inside the loop. C Program to Read the First Line From a File. Using fscanf directly on input is very difficult to get right (what happens if there are four words on a line? what happens if there are only two?) and I would recommend the fgets/sscanf solution.Īlso, as Delan Azabani mentioned. You should probably use %* in place of all your spaces in that case, and check the return value from fscanf. If it were just a matter of matching the newline, you could use "%*%*1" instead of " \n" at the end of the string. Read string with spaces using scanf() function in C programming language - In this program we are going to explain how we can take input of a string with spaces. ![]() This also allows for easier error recovery. You should use fgets to get the line, then sscanf on the string itself. Putting \n in a scanf format string has no different effect from a space. ![]()
