#include <iostream>
#include <fstream>
#include <algorithm>
using namespace std;
int main () {
	ifstream fin ("measurement.in");
	ofstream fout ("measurement.out");
	int z = 0;
	int n;
	fin>>n;
	int day [100];
	string name [100];
	int change [100];
	for (int i=1; i<=n; i++) {
		fin>>day[i]>>name[i]>>change[i];
	}
	int bessiemilk, mildredmilk, elsiemilk;
	bessiemilk = mildredmilk = elsiemilk = 7;
	bool bessie_milk, mildred_milk, elsie_milk;
	bessie_milk = mildred_milk = elsie_milk = true;
	for (int currday=1; currday<=100; currday++) {
		for (int i=1; i<=n; i++) {
			if (currday==day[i]) {
				if (name[i]==("bessie")) {
					bessiemilk = bessiemilk + change [i];
				}
				if (name[i]==("mildred")) {
					mildredmilk = mildredmilk + change [i];
				}
				if (name[i]==("elsie")) {
					elsiemilk = elsiemilk + change [i];
				}
			}
		}
		int maxmilk = max(bessiemilk, max(mildredmilk, elsiemilk));
			bool bessie_milk2 = (bessiemilk == maxmilk);
			bool mildred_milk2 = (mildredmilk == maxmilk);
			bool elsie_milk2 = (elsiemilk == maxmilk);
			if (bessie_milk!=bessie_milk2 || mildred_milk != mildred_milk2|| elsie_milk!=elsie_milk2) {
			z++;
			}
			bessie_milk=bessie_milk2;
			mildred_milk=mildred_milk2;
			elsie_milk=elsie_milk2;
		}
	fout<<z;
}


for these:
bool bessie_milk2 = (bessiemilk == maxmilk);
bool mildred_milk2 = (mildredmilk == maxmilk);
bool elsie_milk2 = (elsiemilk == maxmilk);

how do I make the value of the booleans on the left equal to the validity of the statement (true/false) of the statement on the right? Is this correct already?

bool bessie_milk2 = (bessiemilk == maxmilk);
sure
but please differentiate your variable names


by the way, valid array indices start at 0 and end at size-1

YES.
you can also treat boolean expression results as the integer 0 and 1 which can be very useful (as an array index or the sum of true results, etc).
