Why are all of my booleans setting off as true? - c++

Question

I tested my code out by printing the values out to see why it did not output the value I should be getting. And I found out all of my booleans that were for the string ride were set off as true and I can not seem to get a clue why. I have tried searching the internet up yet I could not find anything. My understanding of the code is not deep enough for me to understand what is going wrong here.
#include <iostream>
#include <string>
using namespace std;
int main() {
//declarations
string ride;
char comp;
int age;
double td, tp, god, rp, sp, ta, tap;
bool fer, bump, zip, pir, test;
//print outs and input
cout<<"What ride would you like to buy a ticket for? "<<endl;
getline(cin, ride);
cout<<"How old are you?"<<endl;
cin>>age;
//functions
//ride
if (ride == "Ferris Wheel"){
rp = rp + 75.00;
fer = true;
}
if (ride == "Bumper Cars"){
rp = rp + 50.00;
bump = true;
}
if (ride == "Zipper"){
rp = rp + 100.00;
zip = true;
}
if (ride == "The Pirate Ship"){
rp = rp + 75.00;
pir = true;
}
//age
//ferris wheel
if (fer = true){
if (age >= 0 && age <= 7){
cout<<"Do you have a companion that is at least 18 years old? Y/N";
cin>>comp;
if (comp == 'Y'){
td = td + .20;
}
else{
cout<<"You need a companion that is at least 18 years old.";
}
}
else if (age >= 8 && age <= 12){
td = td + .10;
}
else if(age >= 13 && age <= 20 ){
td = td + 0.08;

input for ride: The Pirate Ship
input for age: 9
output i get from code:
discount i get from code: 30
partial price : 45
total price : 47.25
output i should be getting from code:
discount i get from code: 7.5
partial price : 67.5
total price : 70.875

Answer 1

I think this is because you didn't initialize your boolean variables. There is no single line, where you set "false". So that, they get random values, i.e. any non-zero value is considered as "true".

Answer 2

Set default value for booleans bool fer = false, bump = false, zip = false, pir = false, test = false;
You are using if wrong.
if (zip = true) // if zip equals true.
if (zip == true) // if zip equals true?
Use else if
//ride
if (ride == "Ferris Wheel"){
rp = rp + 75.00;
fer = true;
}
else if (ride == "Bumper Cars"){
rp = rp + 50.00;
bump = true;
}...
The ride cannot equal "Ferris Wheel" and "Bumper Cars" same time.
