Explain scanf( ) with example.
Understand the Problem
The question is asking for an explanation of various programming concepts and tasks related to the C programming language, such as explaining functions, writing algorithms, and coding exercises.
Answer
The `scanf()` reads input in C using format specifiers, e.g., `scanf("%d", &var);` reads an integer.
The scanf() function in C is used to read input from the standard input (typically the keyboard). It takes a format string, specifying the type of data expected, and arguments where the input will be stored. Example: int num; scanf("%d", &num); reads an integer and stores it in num.
Answer for screen readers
The scanf() function in C is used to read input from the standard input (typically the keyboard). It takes a format string, specifying the type of data expected, and arguments where the input will be stored. Example: int num; scanf("%d", &num); reads an integer and stores it in num.
More Information
The scanf() function allows programmers to read formatted data from input. It's crucial to use the & operator to provide the address of the variable where data will be stored.
Tips
A common mistake is forgetting the & symbol, which is needed to pass the variable’s address to scanf().
