Actually I experimented, stdout used to print in output screen, fprintf used in file. Printf used in fun.

fprintf(fp, "abc....");
This statement writes the text in file pointed by fp pointer in d same way stdout is also a pointer that points to the output device hence.
fprintf(stdout, "abc");
This statement will print value on the screen or on any output device.

Stdout is a standard output. It is used to print the output.

Hi @Indu,
Output will be same, but the only difference is where it prints (i.e. location).
printf - prints the output on terminal.
fprintf - prints output in file, this file can be used for further calculations if necessary.

Then what is the difference between printf and fprintf.
What will be the output if we give printf and what could be the output if it is fprintf?
I want to know the difference.

printf("Hai friends\n"); //This will print output in stdout.
FILE *f=fopen("test.txt","w");
fprintf(f,"%s","HELLO"); // This will print the output in test.txt.
FILE *f=fopen("test.txt","w");
fprintf(f,"%s","HELLO"); // This will print the output in test.txt.
