Formatting of integers
The %d format specifier is implemented for representing integer values. This is used with printf() function for printing the integer value stored in the variable.
Syntax : printf("%d",<variable name>);
Formatting of floating point values
The %f format specifier is implemented for representing fractional values. This is implemented within printf() function for printing the fractional or floating value stored in the variable. Whenever you need to print any fractional or floating data, you have to use %f format specifier.
Syntax : printf("%f",<variable name>);
Formatting of characters
The %c format specifier is implemented for representing characters. This is used with printf() function for printing the character stored in a variable. When you want to print a character data, you should incorporate the %c format specifier.
