Write a program in c to read and store the bio-data into file

C Program to Store Information of a Student Using Structure

It works very much like the printf function we saw in the "Hello, World! For now it may be best to consider this "magic" before we discuss pointers. Tabs and newlines[ edit ] What if, we want to achieve some output that will look like: There is, however, one variation to scanf as compared to printf.

Also display the count of students as indicated above on the left side of each row. I had to read an input file and take the contents and read it into an array of structs.

Once you read data from the file to your array, you are required to calculate and display the following statistics for each exam. Although, this is vulnerable to Buffer overflow. It will be better to have an array for each statistic of size 3, that is an array for lowest values, and so on.

I completed my source code and it runs and gives me the correct output, but I would like second opinions.

Input using scanf [ edit ] The scanf function is the input method equivalent to the printf output function - simple yet powerful. The grade will be based on the total of all the 3 exams which will be out ofand grade will be as follows: Using functional decomposition, write a program to keep records and perform statistical analysis for a class of 9 students.

You will read the input data from an input file scores. You may assume the scores from the file had been validated and they are all valid.

Please note that the comments are for my own personal benefit. It is first stored in what is known as a buffer - a small amount of memory reserved for the input source. A complete listing of all the format specifiers for printf is on Wikipedia. In its simplest invocation, the scanf format string holds a single placeholder representing the type of value that will be entered by the user.

C Programming/Simple input and output

The statistics to be shown will be the: Each line of data for one student will be read from file and then assigned to a struct variable. For more details, see the Wikipedia article on C data types.

The scanf function requires the memory address of the variable to which you want to save the input value.

Program No : 34 :

Sometimes there will be data left in the buffer when the program wants to read from the input source, and the scanf function will read this data instead of waiting for the user to type something. When data is typed at a keyboard, the information does not go straight to the program that is running.

The instructions for the assignment are down below: All escape characters start with a backslash.

C Program to Store Information of Students Using Structure

There are 3 exams, each worth points, during the semester. Each student is identified by a 4-digit student ID with a first name and a last name and followed by three exam scores. Then, I had to solve for some particular statistical data such as finding the lowest and highest scores from the data.

An escape character is a special character that we can write but will do something special onscreen, such as make a beep, write a tab, and so on. The puts function appends a newline character to its output. Even though the source code easily allows readers to understand what is going on, I have included them to help myself stay organized.

This will be a 1-dimensional array.Both of these language bindings might be a very efficient way to read and write HDF5 files. There are also APIs in Fortran, Java, Python, Matlab, C, or C++. So it might make sense to select the language and define the type of data you wish to store first. C Program to Store Information of a Student Using Structure.

This program stores the information (name, roll and marks) of a student and displays it on the screen using structures. To understand this example, you should have the knowledge of following C programming topics.
