Hi! I'm having a problem with printing the totals and averages. It gives me strange numbers like below. Thank you!

fclose(reportFile);

printf("You processed %d employees ",empCount);

getchar();

return 0;

}

Explanation / Answer

Instead of using FORMAT to print the total values and average values, use ReportHeading4 and ReportHeading5 defined earlier in the program. Even if that doesn't work try print the TOTAL and AVERAGE without any formatting and check the result. Let me know if that doesn't work for you.
