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

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%26gt; sum %26gt; output1.txt





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