Why is this output weird?

Im using XCode for Objective C basics.

Here is the code: 

#include <stdio.h>

int main()
{

    int days_in_a_week = 7;
    float cm_to_in = 2.54;

    char the_w;
    the_w = 'W';

    // insert code here...
    printf("%days in a week.\n", days_in_a_week);
    printf("%f cm per in.\n", cm_to_in);
    return 0;
}

the output is cutting off the space and the letter D, in "days" WHY?? output:

7ays in a week.
2.540000 cm per in.
Program ended with exit code: 0

Try This:

printf("%d days in a week.\n", days_in_a_week);

Because the identifier for an integer is %d

in your first printf function you simply didn't recognize that the %d(which is the identifier for an integer) was included along with the string you were trying to print.

However if you ever see a mistake like that again whenever your logging or printing results in the console look at the printed result and see where the error is, once it's spotted,

look back at the string you typed, within the same area should be your error.

Good Luck.
