what exactly, is that supposed to be a string that looks like that or a vector of vectors or sort a vector of vector?

[grand cape]

you are supposed to print triangle numbers?

[iron turtle]

i dont have idea our topic is loop something i think its a string

[iron turtle]

print like [0] and so on

[grand cape]

do you know the formula for those numbers?

[iron turtle]

aithmetic?

[deft solar]

int main()
{
    unsigned int result = 0;
    unsigned int count = 10;

    for (int i = 1; i < count; ++i)
    {
        std::cout << result << '\n';
        result += i;
    }

    std::cout << result << '\n';
}```

i suggest you tu use for loops tho

int main()
{
    unsigned int result = 0;
    unsigned int count = 10;
    unsigned int i = 1;

    while (i < count)
    {
        std::cout << result << '\n';
        result += i++;
    }

    std::cout << result << '\n';
}```

for loop is much easier yes

[deft solar]

Basically what it does is:
loop an amount of times each time it increment a variable of the current index

in the example that you showed it did 10 times

[grand cape]

also you shouldn't just tell someone the solution like this

[deft solar]

whyh ?

[grand cape]

whyh?

pff

[grand cape]

pff?

[deft solar]

jealous ?

poor guy

[grand cape]

where did this come from

[deft solar]

what ?

[iron turtle]

i see a bit very close

[grand cape]

why did you just become mad at me?

[deft solar]

by the current looping index*

[iron turtle]

do you have idea how to put this inside the brackets?

[deft solar]

int main()
{
    unsigned int result = 0;
    unsigned int count = 10;
    unsigned int i = 1;

    while (i < count)
    {
        std::cout << '[' << result << ']' << ' ';
        result += i++;
    }

    std::cout << '[' << result << ']' << '\n';
}```
