For example, if the user enters 12, the program should display 1122. 4 Operators Now that you’ve been introduced to the concepts of C data types, variables, and constants, it is time to learn how to manipulate their values. C provides a rich set of operators that are used to build expressions and perform operations on them. In this chapter, we’ll present some of C’s most important operators. We’ll introduce the rest gradually over the next several chapters, and you’ll see how to apply them when building more complex programs.
3/8/2020). scanf() Return Value A function may return a value to the calling program, and scanf() returns the number of data items that were successfully converted and assigned to program variables. scanf() fails if the values entered don’t match the types or order of the conversion specifiers. 34 C: From Theory to Practice In the following example, scanf() expects an integer first and then a float number: int i; float j; scanf("%d%f", &i, &j); In this case, scanf() will return 2. Otherwise, if the user enters a different value, like two float numbers or a float number and then an integer, scanf() will fail.
Type Casting C allows the programmer to convert the type of an expression to another type. This conversion is known as type casting. Cast expressions have the following form: (data_type) expression 24 C: From Theory to Practice where data _ type specifies the type to which the expression should be converted. 34; the cast expression a = (int)c converts the value of c from float to int and make a equal to 2. After being used in the cast expression, c will be treated again as float. 6) converts the result of the addition to type int and assigns it to b.
