Write a C Program to Display The Size of Different Data Types

Write a c program to display the size of different data types. Here is one thing noted down the size of Datatype maybe depends upon your Operating System. Operating System You Are using maybe 32 Bit or 64 Bit. The data type of problems can handle easily in C++. C++ have a "sizeof" Operator to find the size of any datatype following the given syntax. The size of data types in c can be solved by using the following syntax.

Syntax: sizeof( datatype )

C Program to Display The Size of Different Data Types

#include <stdio.h>

int main() {
  printf("Size of Int Data Types in C = %2d bytes \n", sizeof(short int));
  printf("Size of Long Int Data Types in C = %2d bytes \n", sizeof(long int));
  printf("Size of Float Data Types in C = %2d bytes \n", sizeof(float));
  printf("Size of Double Data Types in C = %2d bytes \n", sizeof(double));
  printf("Size of Long Double Data Types in C = %2d bytes \n", sizeof(long double));
  printf("Size of Char Data Types in C = %2d bytes \n", sizeof(char));
  return 0;
}
