简单的循环我不知道

Question

I'm kind of new to C++ so last night I thought of something. I want to print out numbers from 1-100 but with 10 numbers per line. I'm aware my code is below is wrong as it just prints 1-100 vertically. If anyone can shed some light to my question, it would be greatly appreciated. Thanks for reading :)

#include <iostream>
using namespace std;

int main() {

    for(int x = 1; x <= 100; x++) {
        cout << x << endl;

    }
}

Answer 1

So you want to print 10 numbers, then a carriage return, and then 10 numbers, then a carriage return, and so on, correct?

If so, how about something like:

for(int x = 1; x <= 100; x++) {
    cout << x << " ";
    if ((x%10)==0) cout << endl;
}

Answer 2

Use the modulo operator % to determine if a number is a multiple of another:

for(int x = 1; x <= 100; x++) {
    if( x % 10 == 0 ) cout << endl;
    cout << x << " ";
}

Answer 3

How about

int main() {
       for(int x = 1; x <= 100; x++) {
        cout << x << " " ; //Add a space
        if ( x % 10 == 0 ) {
            cout << endl //Put out a new line after every 10th entry?
        }
    }
}

Answer 4

Print new line when it can be device by 10.

for(int x = 1; x <= 100; x++) {

    cout << x << ",";

    if ((x % 10) == 0) {

        cout << endl;
    }
}

Answer 5

    for(int i=1; i<=100; i++) {
        i%10==0 ? cout << i<<endl : cout<<i<<" ";
    }
