8. Write a program in C to demonstrate and decide the size of int, float, char, and double data types.

#include <stdio.h>
int main()
{
 int a=5;
 float b=50.34;
 char ch=’C’;
 double d=2345346.765;
 printf(“\n value of a=%d”,a);
 printf(“\n Value of b=%.2f”,b);
 printf(“\n Value of Ch=%c”,ch);
 printf(“\n value of d=%lf”,d);
 printf("\nSize occupied by int data type: %lu bytes ", sizeof(int));
 printf("\nSize occupied by float data type: %lu bytes ", sizeof(float));
 printf("\nSize occupied by character data type is : %lu byte ", sizeof(char));
 printf("\nSize occupied by double data type: %lu bytes ", sizeof(double));
 return 0;
}
Output:
 value of a=5
 Value of b=50.34
 Value of Ch=C
  value of d=2345346.765
 Size occupied by int data type: 4 bytes
 Size occupied by float data type: 4 bytes
 Size occupied by character data type is: 1 byte
 Size occupied by double data type: 8 bytes
