C programming reading a file into an array




















After using a single line fgets , if I prnt the output I get only the 1st element. According to the manual page : "fgets reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

I would paste my whole program attempt, but the remote desktop won't let me copy and paste back on to my original computer I mean I just did it a couple of minutes ago.. But anyways back to the problem.. I want to do this without the use of "get" or "put", because my understanding of those functions are limited. I finally got to the remote desktop to let me copy and paste I would really appreciate it.

First of all, newline is a very bad name for a counter. Maybe numLines would make more sense. Use fgets instead of fscanf to read strings. And isn't check a character array? Hence, after it is given a command to print the elements, all the five elements will be printed as per the order they were entered into the array.

If the condition is true then it reads the entered element,initialized to a[i] using scanf function and the function input calls itself by increasing i value. If the condition is true then it prints the array element a[i] using printf function and the function output calls itself by increasing i value by 1.

The methods discussed in the current piece are as follows: Using Standard Method Using Function Using Recursion An array is a collection or a sequential order to various elements, with or without a particular order. As you can see, in this array, the size of the array is defined at first. The size of this array is 5. After that, the elements are entered accordingly for the array. Improve this answer. It would nice to explain that s he wants to scan for a string, not a single character.

The variable i is not needed in the first place. Samaras; Added that. Show 2 more comments. Then you of course need to index into that array in the loop, i. S Karthikeyan.

Matrix A and B of different size may be stored in different input file if required. Scan and assign matrix A and B as array using fscanf function and for loop Perform matrix operations a.

Add matrix A and B b. Subtract matrix A and B c. Multiply matrix A and B Use conditional statement if or switch for switching between 3, 4 and 5 elements matrix. Print all input matrices and results obtained in a new file called output.
