Read One Line at a Time from a File using fgets() This program will work perfectly fine and it will take the entire string as input from the keyboard and displays it on the output screen. Please note that C does not check for array bounds, so be careful not to input more character that can be stored in the string variable used.Ī complete program to demonstrate working of gets : #include The last program can be also written as : char instr It will reads a line from the keyboard and displays it on the screen. Unlike scanf, it does not skip whitespaces. It reads characters from the keyboard until a new line character is encountered and then appends a null character to the string. #includeĪnother method of reading a string of text containing whitespaces is to use the library function gets available in the header file. Is entered and the null character is then inserted at the end of the string. The reading is terminated when the new line character ('\n') Thus, an entire line of text can be read and stored in an array. We can use it repeatedly to read successive single characters from the input and place them into a character array. char instr Ī similar method to above: char instr #HOW TO DECIPHER TEXT IN C CODE#However, C supports a format specification known as the edit set conversion code % that can be used to read a line containing a variety of characters, including whitespaces. We have seen that scanf with %s or %ws can read only strings without whitespaces. It will take four words in four different character arrays and displays on the output screen. Printf("%s %s %s %s" ,instr1,instr2,instr3,instr4 ) Printf("Enter the string of four words\n") Reading Multiple Words to Form a Line #includeĬhar instr1,instr2,instr3,instr4 To overcome this problem we can make different arrays for all the words present in the string. If we give "WELCOME TO OPENGENUS" as input it will only read WELCOME and displays it as output. It will assign the string "HELLO" to instr1 and "BOY" to instr2. If we want to read the entire line "HELLO BOY", then we may use two character arrays of appropriate sizes. Note that unlike previous scanf calls, in the case of character arrays, the ampersand (
