Two errors I don't know how to deal with.
Hello. I am getting the following two errors on the code below, and I don't know how to fix them. Can someone help me please? The function is designed to calculate the weighted average of homework, quiz, and test grades read in from an input file, as well as a later function that calculates the total average after a dropped homework grade.
The errors are:
Code:
1>MSVCRTD.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup
1>C:\Users\Trey\documents\visual studio 2010\Projects\Program 5\Debug\Program 5.exe : fatal error LNK1120: 1 unresolved externals
The program is as follows:
Code:
// Trey Brumley
// CMPS 1043-101
// December 3, 2012
// Program 5 - Arrays

#include <iostream>

void droppedGrade();
