Writes the C string pointed by format to the stream.If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers. After the format parameter, the function expects at least as many additional arguments as specified by format.
C programming, exercises, solution: Write a program in C to read the file and store the lines into an array.
In this tutorial we will learn to read and write multiple data in files in C programming language. In the previous tutorials we have learned how to read and write characters in files in C and how to read and write integers in files in C.In both the cases we worked with single character and integer at a time.
Task. Write two equal-sized numerical arrays 'x' and 'y' to a two-column text file named 'filename'. The first column of the file contains values from an 'x'-array with a given 'xprecision', the second -- values from 'y'-array with 'yprecision'.
Redirection. One way to get input into a program or to display output from a program is to use standard input and standard output, respectively.All that means is that to read in data, we use cin (or a few other functions) and to write out data, we use cout. When we need to take input from a file (instead of having the user type data at the keyboard) we can use input redirection.
Print an integer in C language: a user inputs an integer, and we print it. Input is done using scanf function, and the number is printed on screen using printf.

Finally, the string is converted into an integer and printed on the screen. You can learn how to write your own C programs with this course. Example 2: A Program to Convert String to Integer Using the atoi() Function. atoi() is a function that converts a string data type to integer data type in the C language. The syntax of this function is as.
