Input: scanf("%c", &charVariable); Output: printf("%c", charVariable);
For taking input in C, we use the built-in function of the C scanf(). scanf() method reads the input from standard input stream stdin and scans that input as per the type specified. scanf(“%A”, &variableOfAType); The above syntax is for taking input from the user.
The input ( ) function helps to enter data at run time by the user and the output function print ( ) is used to display the result of the program on the screen after execution.
In Python, we use the print() function to output data to the screen. Sometimes we might want to take the input from the user. We can do so by using the input() function. Python takes all the input as a string input by default.
Printf() and Scanf() are inbuilt library functions in C language that perform formatted input and formatted output functions. These functions are defined and declared in stdio. h header file. The 'f' in printf and scanf stands for 'formatted'.
The scanf function reads input from the console and parses it. It has no means of printing anything.
The printf() function sends a formatted string to the standard output (the display). This string can display formatted variables and special control characters, such as new lines ('\n'), backspaces ('\b') and tabspaces ('\t'); these are listed in Table 2.1. Table 2.1. Special control (or escape sequence) characters.
The printf() function is used to format and print a series of characters and values to the standard output. The format argument is a string containing C language conversion specifications.
In C programming language, %d and %i are format specifiers as where %d specifies the type of variable as decimal and %i specifies the type as integer. In usage terms, there is no difference in printf() function output while printing a number using %d or %i but using scanf the difference occurs.
The “%d” in scanf allows the function to recognise user input as being of an integer data type, which matches the data type of our variable number. The ampersand (&) allows us to pass the address of variable number which is the place in memory where we store the information that scanf read.

Generally, printf() function is used to print the text along with the values. If you want to print % as a string or text, you will have to use '%%'. Neither single % will print anything nor it will show any error or warning.
This is the code: char ch; printf("Enter one char"); scanf("%c", &ch); printf("%c\n",ch);
In short, the statement. scanf(“%[^\n]%*c”,name); means that all the characters entered as the input, including the spaces, until we hit the enter button are stored in the variable, name; provided we allocate sufficient memory for the variable.
%d takes integer value as signed decimal integer i.e. it takes negative values along with positive values but values should be in decimal otherwise it will print garbage value.
%d tells printf that the corresponding argument is to be treated as an integer value; the type of the corresponding argument must be int .
The scanf function allows you to accept input from standard in, which for us is generally the keyboard. The scanf function can do a lot of different things, but can be unreliable because it doesn't handle human errors very well. But for simple programs it's good enough and easy to use. scanf("%d", &b);
The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations. To use printf() in our program, we need to include stdio.h header file using the #include <stdio.h> statement.
Printers. Printer is an output device, which is used to print information on paper.
The input() function allows a user to insert a value into a program. input() returns a string value. You can convert the contents of an input using any data type. For instance, you can convert the value a user inserts to a floating-point number. input() is supported in Python 3.
%ld. Long Integer Format Specifier. It is used when data type is of long int which stores a long integer value from range [−2,147,483,647, +2,147,483,647]. %lld. Long Long Integer Format Specifier.
The %s means, "insert the first argument, a string, right here." The %d indicates that the second argument (an integer) should be placed there. There are different %-codes for different variable types, as well as options to limit the length of the variables and whatnot. Control Character.
