Finally, the file is closed using fclose(). File pointer, formatted string and the variable list is passed to the fprintf function. If it opens successfully, the formatted string is printed to the file. If it is not opened, it will give unable to open the file error. Printf(“Data is written successfully to the file”) Refer the below code to understand the functionality of fprintf (). The syntax for fprintf is as follows įprintf(file pointer, “format specifier”, “list of variables”) The fprinf function is used to output a formatted string to a file. To print double quotes, the programmer can use as follows. Printf(“value of a is %d \t value of b is %d\n”, a,b) will give a space or a tab between value of a and value of b. This will print “a” and “b” values in separate lines. Printf(“value of a is %d \n value of b is %d\n”, a,b) Refer bellow example.įormatted string can also have escape sequences. Printing floating point numbers is as follows. ![]() Printf(“Value of a is %d and value of b is %d\n”, a,b) “a” and “b” are integers, so they are specified with %d. Method to print a formatted string is as follows. If the user does not want to print a formatted string, it is possible to print the string as it is. Printf(“formatted string”, “list of variables”) The syntax of printf function is as follows. “printf” function is used to give an output in a formatted way to a display device such as computer screen. Side by Side Comparison – printf vs fprintf in Tabular Form Similarities Between printf and fprintfĥ. The key difference between print and fprintf is that printf is a C function used to print a formatted string to a standard output stream which is the computer screen, while fprintf is a C function to print a formatted string to a file. This article discusses the difference between these two functions. Two main built-in functions in C language are printf() and fprintf(). The programmer can use them without implementing from the beginning. The language provides built-in functions. The programmer creates user-defined functions. There are built-in functions and user-defined functions. It indicates the starting point of the execution. In programming language such as C language, main() is a function. Therefore, the program is divided into several functions. It is not possible to write all statements in the same program. A function is a set of instructions to perform a specific task.
