What is the difference between %S and %C?
%c is the format specifier for character and %s is the format specifier for string(character array).
A string is a collection of characters stored in contiguous memory locations.
In other words, it is an array of characters.
We can use %c to scan character type input from the users..
What is the difference between char and string?
Char is a single alphabet where as String is a sequence of characters. Char is primitive datatype where as String is a class. A char holds a single character, while a string holds lots of characters. char is a primitive type, and it can hold a single character.
How do you represent a character in C?
Using C char type In order to declare a variable with character type, you use the char keyword followed by the variable name. The following example declares three char variables. char ch; char key, flag;.
What is printf () in C?
“printf” is the name of one of the main C output functions, and stands for “print formatted”. printf format strings are complementary to scanf format strings, which provide formatted input (parsing). … The format string itself is very often a string literal, which allows static analysis of the function call.

How does %s work in C?
4 Answers. %c and %s are part of the printf() functions in the standard library, not part of the language itself. … %c deals with a char (that is, a single character), whereas %s deals with a char * (that is, a pointer to an array of characters, hopefully null-terminated).
What is %d in C called?
The first argument to printf is a string of identifiers. %s refers to a string %d refers to an integer %c refers to a character. Therefore: %s%d%s%c\n prints the string “The first character in sting “, %d prints i, %s prints ” is “, and %c prints str.
What does int * mean in C?
There are no pointer types in C! So, “int*” means nothing. The asterisk is always bound to the element written right of it, it belongs to the element right to it. “*i” is an int. And because of *i is an int, it follows that i is a pointer to int.
What is float in C programming?
Float is a shortened term for “floating point.” By definition, it’s a fundamental data type built into the compiler that’s used to define numeric values with floating decimal points. C, C++, C# and many other programming languages recognize float as a data type. Other common data types include int and double.
What is S in programming?
S is a statistical programming language developed primarily by John Chambers and (in earlier versions) Rick Becker and Allan Wilks of Bell Laboratories. The aim of the language, as expressed by John Chambers, is “to turn ideas into software, quickly and faithfully”.

What does * mean in C?
double* means a pointer to a double variable. double** means a pointer to a pointer to a double variable. In the case of the function you posted, it is used to create a sort of two-dimensional array of doubles. That is, a pointer to an array of double pointers, and each of those pointers points to an array of pointers.
What is the use of * in C?
“*” Operator is used as pointer to a variable. Example: * a where * is pointer to the variable a. & operator is used to get the address of the variable. Example: &a will give address of a.
What is %C in C language?
%d is used to print decimal(integer) number ,while %c is used to print character . If you try to print a character with %d format the computer will print the ASCII code of the character.
What is the difference between char array and string?
String refers to a sequence of characters represented as a single data type. Character Array is a sequential collection of data type char. Strings are immutable. Character Arrays are mutable.
What is #include in C?
The #include directive tells the C preprocessor to include the contents of the file specified in the input stream to the compiler and then continue with the rest of the original file.
