Why there is no output of the following code?

scanf("%2d%d%f%5s", &x, &y, text); printf ("%d %d %s", x, y, text) ; // where x and y are integer variables and text is character type array We've input as 1234 5.7 elephant

Krishna Kumar Then, you don't need that input field! ⟹ Make sure order of format and variable data types match up. Go through the lesson again, you'll better understand and use Daljeet Singh 's advice!

Krishna Kumar You should correct the scanf() function for floating data type: %f scanf("%2d %d %*f %5s", &x, &y, text); • A format specifier can include several options along with a conversion character: %[*][max_field]conversion character ⟹ The optional * will skip the input field!!

Krishna Kumar read about format specifiers here : https://www.geeksforgeeks.org/format-specifiers-in-c/ in your code you are using %d instead use %s // try inserting code by clicking @ "insert code" https://code.sololearn.com/c3e7aVZ96l1P/?ref=app

Your scanf() has four format specifiers (%d, %f etc.) for three variables

Krishna Kumar add this (might come handy in future) to you code* char text[5]="abcd"; printf("%8s\n",text); printf ("%*s\n",0xf, text);

Danijel, but what if we don't want to skip the input float field and still print the values of x and y?

But here scanf("%2d%d%f",&x,&y); printf ("%d",x); printf("\n%d",y); //it also has greater format specifiers(3) as compared to lesser variables (2) but it gives output! Here x and y are also integer type.
