程序代码：

void fun (char *s, int a, double f)
{
    /**********found**********/
    1 * fp;
    char ch; &
    fp = fopen("filel.txt", "w");
    fprintf (fp, "% S % d %f\n", % '%', f);
    fclose(fp);
    fp = fopen("filel.txt", "r");
    printf("\nThe result:\n\n");
    ch = fgetc(fp);
    /**********found**********/
    while (!feof ( 2 ))
    {
        /**********found**********/
        putchar( 3 );
        ch = fgetc(fp);
        putchar('\n');    
    }
    fclose(fp);

}
int main( )
{
    char a[10] = "hello!"; 
    int b = 12345;
    double c = 98.76;
    fun(a, b, c);
}
