How to display the output in a file using C program?

Question

I need to display the whole output produced on the userscreen to be displayed in a file using C program. Any one who knows please help me.

Answer 1

Use fprintf( )


fprintf( this space for pointer to a file,"Whatever you want to output in file")

example:

out = fopen("final.txt","w"); // out is pointer to file
fopen opens file final.txt
w means to write to file

fprintf(out, "Welcome to Hollywood\n");

when you build and run program, and open the file, it should have Welcome to Hollywood in it.

****Make sure you save the file in the projects folder of the program

Answer 2

.

You can use fprintf() to directly send the output to files.

Otherwise you can write ordinary C program and then when executing it in the prompt, give a file name with a greater than symbol.

eg.

c:/TurboC/bin> sum > output1.txt

The above eg would print the ouput of the program "sum" in to the file ouput1.txt.
