Printing Variable Contents

Use the printf function with formatting options.

<source lang="cpp">#include <stdio.h> main(){

 int x;
 float y;
 char c;
 x = -4443;
 y = 554.21;
 c = "M";
 printf("\nThe value of integer variable x is %d", x);
 printf("\nThe value of float variable y is %f", y);
 printf("\nThe value of character variable c is %c\n", c);

}</source>

The value of integer variable x is -4443
      The value of float variable y is 554.210022
      The value of character variable c is M

Conversion specifiers are made up of two characters: % and a special character.

The special character tells the program how to convert the data.

Conversion Specifier Description %d Displays integer value %f Displays floating-point numbers %c Displays character
