Scanf In subject area: Computer Science 'Scanf' is a standard input function in C programming that reads input values based on a specified format from the keyboard. It is used to read different data types like
scanf("%d", &b); c = a + b; printf("%d + %d = %d\n", a, b, c); return 0; } You can also delete the b variable in the first line of the above program and see what the compiler does when you forget to declare a variable. Delete a semicolon and see what happens. Leave...
There is no such promotion withscanfarguments, which are actuallypointers. So all types must be exactly specified. In addition there are security concerns with input that don't apply to output. (These will be discussed below. In particular,neveruse thegets()function in production-quality C ...

rather than errors in the coding of the function itself. But the function is so complex that to a new programmer (and probably most veterans) this function is an enigma. scanf() is a Jack of all trades function. It has been designed to handle as many input types as possible, from simp...
