Introduction

The printf() function is ideal for displaying number values.

To display number values, you use conversion characters in the function's formatting string.

The following code displays an integer and a float Values

Demo

#include <stdio.h> 

int main() //from  ww w . j  a  va  2s.c  o m
{ 
   printf("The value %d is an integer.\n",986); 
   printf("The value %f is a float.\n",98.6); 
   return(0); 
}

Result

The text included in a printf() function is a formatting string. For example 

"The value %d is an integer.\n"
"The value %f is a float.\n"

The printf() function's formatting string can contain plain text, escape sequences, and conversion characters, such as the %d and the %f.

These conversion characters act as placeholders for values and variables that follow the formatting string.

For the %d placeholder, the integer value 986 is substituted.

The %d conversion character represents integer values.

For the %f placeholder, the float value 98.6 is substituted.

The %f conversion character represents floating-point values.

The %d and %f are only two of many placeholders for the printf() function's formatting string.
