    printf("Enter an integer:");
    scanf("%d", &n);
    for (i = 1; i <= 10; ++i)

        printf("%d * %d = %d \n", n, i, n, n * i);
    }

What I have tried:

I think the issue is with the math

Solution 2

very simple you need to change:

C++

int n, i;

and remove the third parameter in your print.

Be more careful in writing and reading code ;-)

Solution 1

We can't tell you: we have no idea what that code is meant to do, and since the "math" is so basic it's unlikely to be that.

But ... why do you specify three output values in the format string "%d * %d = %d \n" and provide four output values in the parameter list: n, i, n, n * i
n is in there twice ...

Oh that's where my problem is. Thanks.

Is this better?

#include <stdio.h>
int main() {
int n, i;
printf("Enter an integer: ");
scanf("%d", &n);
for (i = 1; i <= 10; ++i) {
printf("%d * %d = %d \n", n, i, n * i);
}
return 0;
}

Could be.

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So we have no idea what your code is meant to do unless you tell us ...

Sure, I'll tell you. So, this code basically sets up a multiplication table, with answer, like you enter 3, it writes 3 x 1 = answer, 3 x 2 = answer, 3 x 14 = answer, and so on.
