:) Good one. It checks my eye sight. This piece of code would result in an error: "undefined symbol Y". Note: 'scanf( )' not only scans and loads the values entered by users into variables, but it also returns a number which is the count of the number of variables that are successfully scanned by itself. So, in this example if the upper case 'Y' in 'scanf( )' is replaced with lower case 'y', the scanf( ) would return 2 on successfully scanning the input values (say 10 and 20) to memory. read less

Output is 2. why? ans. printf function will count the number of variables that has been scanned because you specify %d which refers to integer.

Hi Pravalika, First thing is you should not ask questions like this (o/p of program etc..), as you can always verify with any compiler you use. You should always ask questions like why such thing..? (Ex. you can ask why the o/p of above program is 5?) Thanks, Janardhan.

It would not compile at very first. So, there is no scope to run this code. Finally, it would not print anything on the output window.
