What is the difference between scanf and getchar

Effectivly it is a fgetc stdin. This function return the character read from the keyboard. Each function reads characters, interprets them according to a format, and stores the results in its arguments. It prints the passed string with a newline and returns an integer value. The return value depends on the success of the writing procedure. Thus, this is the main difference between scanf and getchar. Please find below the description and syntax for each above file handling functions.

The getchar function obtains a character from stdin. When the user provides a character, it displays on the console and waits until the user press the Enter key.

Then, the printf function displays that character on the console. Figure 3: Another C program with getchar. Finally, the printf function displays that value on the console. Thus, this is the main difference between scanf and getchar. Furthermore, while scanf function takes the format string and variables with their addresses as parameters, the getchar function does not take any parameters. Hence, this is another difference between scanf and getchar.

Moreover, how each of them function is an important difference between scanf and getchar. The scanf reads data according to the format specifier; it describes the data types the user sends through the keyboard.

However, getchar reads a single character from the keyboard. In brief, scanf and getchar are two functions available in C language. Python Strings With Examples , Available here. She is passionate about sharing her knowldge in the areas of programming, data science, and computer systems.

In such condition type conversion type promotion takes place to avoid loss of data. In type casting, a data type is converted into another data type by a programmer using casting operator. Whereas in type conversion, a data type is converted into another data type by a compiler.

Type casting can be applied to compatible data types as well as incompatible data types. In computer science, type conversion, type casting, type coercion, and type juggling are different ways of changing an expression from one data type to another. An example would be the conversion of an integer value into a floating point value or its textual representation as a string, and vice versa. The main idea behind type conversion is to make variable of one type compatible with variable of another type to perform an operation.

So, you need to type cast int variable to float to make them both float type for finding the sum. Type promotion in C is a method to convert any variable from one datatype to another.
