This code displays the amount of memory (in bytes) that is set aside for various types of data in C. To find out how big an int, float, double, or char is, you can use the sizeof() function. The answer is then shown in bytes by the printf() function. It is important to know that different types of data need different amounts of memory when writing programs that work well.<\/p>\n\n\n
