{
std::string foods[5];
int size =
std::string temp;

for(int i = 0; i < size; i++){
std::cout << "Enter in food you like or 'q' to quit #" << i + 1 << ": ";
std::getline(std::cin, temp);
if(temp == "q"){
break;
}
else{
foods[i] = temp;
}

std::cout << "You like the following food:\n";

for(int i = 0; !foods[i].empty(); i++){
std::cout << foods[i] << '\n';

Good Video. Let's defeat the YT algorithm.

So i'm pretty sure using !foods.empty in the for loop like that, will make it out of bounds when entering 5 elements. So I changed this, and i'm sure its better, nested inside the for loop add the !foods thing in a if statement. Like this.
for(int i = 0; i < size; i++){
if(!foods[i].empty()){
std::cout << foods[i] << '\n';
}
}
Thanks so much bro code for your tutorials man, I'm learning so much!

Do we really have to make a new variable "food" to call out the input value? Can't we display the value thru cout and put the variable "foods" to display the input value?

And why exactly we divide the getsize foods[5] to getsize foods [0] where as the second one has no value?

hi, is it normal if i have difficulties understanding some of theses concepts?(this one wasn't hard but i've been having a hard time on these last videos i watched)

I get a "Segmentation error", but if I use 'q' before finishing the 5 foods the error does not show

#include <iostream>

using namespace std;

int main()
{
string foods[5];
string temp;

for (int i = 0; i < size(foods); i++)
{
cout << "Enter food what u like or 'q' to quit #" << i + 1 << ": ";
getline(cin, temp);
if (temp == "q") {
break;
}
else {
foods[i] = temp;
}
}

for (int i = 0; i < size(foods) && !foods[i].empty(); i++)
{
cout << foods[i] << "\n";
}

return 0;
}

for (int i = 0; !foods[i].empty(); i++) - I've never thought about doing this check before, expanding my Thinker
