Declaring a variable is just like with any other type: double price = 9.95; Printing uses the format specifier %lf (%lg, %le or %la are equivalent). %e can be used to print value in exponential format of float or double value. » Facebook In C, there is a format specifier in C. To print 4 digits after dot, we can use 0.4f in printf(). Writes the C string pointed by format to the standard output ().If format includes format specifiers (subsequences beginning with %), the additional arguments following format are formatted and inserted in the resulting string replacing their respective specifiers. » CS Organizations C Output. Output: Value of var = 789 Value of var using single pointer = 789 Value of var using double pointer = 789. %e can be used to print value in exponential format of float or double value. If the compiler that you’re using conforms to this standard then all the features and properties should be available to you. printf("Value of var = %d\n", var ); printf("Value of var using single pointer = %d\n", *ptr2 ); printf("Value of var using double pointer = %d\n", **ptr1); return 0; } chevron_right.

Web Technologies: So, we can use both %f … %p pointer. %n Number of characters written by this printf. » Embedded C Don't try to display a (decimal) float/double number using the integer format specifier, %d, as this displays unexpected values!Similarly, don't use %f for displaying integers. In C language, we have data types for different types of data, for integers, it's int, for characters it's char, for floating-point data, it's float, and so on.For large integers, you can use long or long long data type. Other format specifiers are: %d - int (same as %i) %ld - long int (same as %li) %f - float %lf , %g - double %c - char %s - string %x - hexadecimal; A complete listing of all the format specifiers for printf() is on Wikipedia.
