CBCS C Program to Find the Size of int, float, double and char
Dear Friends, This program declares 4 variables of type int, float, double and char. Then, the size of each variable is evaluated using sizeof operator.
To understand this example i.e CBCS C Program to Find the Size of int, float, double and char, you should have the knowledge of following C programming topics:
- C Programming Data Types
- C Programming Constants and Variables
- C Programming Input Output (I/O): printf() and scanf()
# CBCS C Program to Find the Size of a variable
#include <stdio.h>
int main()
{
int integerType;
float floatType;
double doubleType;
char charType;
// Sizeof operator is used to evaluate the size of a variable
printf("Size of int: %ld bytes\n",sizeof(integerType));
printf("Size of float: %ld bytes\n",sizeof(floatType));
printf("Size of double: %ld bytes\n",sizeof(doubleType));
printf("Size of char: %ld byte\n",sizeof(charType));
return 0;
}
Output
Size of int: 4 bytes Size of float: 4 bytes Size of double: 8 bytes Size of char: 1 byte
In this program, 4 variables integerType, floatType, doubleType and charType are declared having int, float, double and char type respectively.
Then, the size of each variable is ascertained using sizeof operator.
