Writing to a file

[BrokenBoxJC]

Hi, I'm relatively new to C, so this will probably seem really easy to most of you. Here's what I have to do:

Write a C program to read an integer and a floating point number from the console and write them to a text file called "exercise3.txt".

I can do the first part of this no problem, it's writing to the file that I can't work out. I would really appreciate some help with this guys, thanks.

Use fopen() to open the file
Use fprintf() just like you would printf()

In fact,
fprintf( stdout, "hello world\n" );
printf( "hello world\n" );
are the same thing.

Use fgets() to read from the keyboard, remove the '\n' character from the end of the string.
use atoi() to convert a string to an integer
use atof() to convert a string to a float.
then do what Salem said.

Here is a sample of code that does what I think you want it to:

#include <stdio.h>

void main( void )
{
    // Your integer
    int Integer;
    // Your floating point number
    float FloatingPoint;
    // your file
    FILE* File;

    printf("Please enter an integer: ");
    // read the integer;
    scanf("%d", &Integer);

    printf("Please enter a floating point number: ");
    // read the floating point number
    scanf("%f", &FloatingPoint);

    // Open the file. The "w" opens the file for writing
    File = fopen("exercise.txt", "w");

    // Write the integer
    fprintf(File, "%d ", Integer);

    // Write the floating point number
    fprintf(File, "%f", FloatingPoint);

    // Close the file
    fclose(File);
}

I hope that the code works. I don't have C on this computer so I didn't test it. lol. You might need another header file or something. Good Luck!
