How to print variable multiple times with one printf statement in C

Question

After searching stack overflow and going through several tutorials I still can't find out how to print a variable multiple time with one printf statement.

This is what I want to get as a result:

1111111111

2222222222

3333333333

by using something like this:

for(int i=1; i<4; i++)

{
    printf("%d", i);   //it would be great to add something here
}

But without another for loop!

Or it can be easily asked like this, I want printf to print variable int i=1; multiple times in a row without loops. So output would be 1111111111

`printf( "%d%d%d%d\n", i, i, i, i )` springs to mind. Any way to be more specific? — DevSolar, Mar 21 '17 at 08:12

You have to use a second loop, like this :

int i, j, number = 1;
for (i = 0; i < 4; i++){
    for (j = 0; j < 3; j++){
        printf("%d", number);
    }
    printf("\n");
    number++;
}

where 4 is the number of different numbers you want to print and 3 is the number of times you want to print a number. In your case, this will print :

111

222

333

444

Otherwise, you have to specify manually the number of arguments in printf :

int i = 1;
printf("%d%d%d\n", i, i, i);

So the answer is...it is not possible to do what I wanted on the way I wanted. The best way is to use another for loop inside existing one.

Thank you all for your answers.

it is impossible to print it without loops(for, while, do while). you can also use goto statement but it is not recommended.

        int counter = 1;
label1: printf("1");
        counter ++;
        if (counter <= 10)
           goto label1;

as I said, using goto is bad. so i recommend loops.
