If you lie to printf(), you get what you deserve. When you tell printf() to expect an int, it treats whatever you pass like an int. When you tell printf() to expect a float, it treats whatever you pass like a float. If whatever you pass doesn't have a compatible byte representation, don't be surprised when you get garbage.
On success, the function returns the number of items successfully read. This count can match the expected number of readings or fewer, even zero, if a matching failure happens.
In the case of an input failure before any data could be successfully read, EOF is returned.
then why does scanf returns 1 in following case if we give a floating point variable as input..
Because scanf() reads until the first invalid character, and if there were valid characters before that such that a conversion can be performed the the conversion will succeed. The first part of a floating-point value up to the radix is a valid integer.
I am writing a java program that needs to execute shell commands, so I wrote a function that would take the command to execute as a string (ie: "mkdir ~/Folder1") and execute that command with the shell. Here is the function:
Runtime run = Runtime.getRuntime();

I don’t want at this stage work on a big separate project as I've already got plenty ...
