Display the sizes and ranges for each of C's data types

C Basic Declarations and Expressions: Exercise-86 with Solution

Write a C program to display the sizes and ranges for each of C's data types.

Sample Solution:

C Code:

#include <stdio.h>   // Include standard input/output header file
#include <stdint.h>  // Include header for fixed-size integer types
#include <inttypes.h> // Include header for format specifiers for integer types

int main( void )
{
printf( "Size of C data types:\n\n" ); // Print title
printf( "Type               Bytes\n\n" ); // Print column headers
printf( "--------------------------------\n"); // Print separator line

  // Print size of various data types
printf( "char                 %lu\n" , sizeof( char )               );
printf( "int8_t               %lu\n" , sizeof( int8_t )             );
printf( "unsigned char        %lu\n" , sizeof( unsigned char )      );
printf( "uint8_t              %lu\n" , sizeof( uint8_t )            );
printf( "short                %lu\n" , sizeof( short )              );
printf( "int16_t              %lu\n" , sizeof( int16_t )            );
printf( "uint16t              %lu\n" , sizeof( uint16_t )           );
printf( "int                  %lu\n" , sizeof( int )                );
printf( "unsigned             %lu\n" , sizeof( unsigned )           );
printf( "long                 %lu\n" , sizeof( long )               );
printf( "unsigned long        %lu\n" , sizeof( unsigned long )      );
printf( "int32_t              %lu\n" , sizeof( int32_t )            );
printf( "uint32_t             %lu\n" , sizeof( uint32_t )           );
printf( "long long            %lu\n" , sizeof( long long )          );
printf( "int64_t              %lu\n" , sizeof( int64_t )            );
printf( "unsigned long long   %lu\n" , sizeof( unsigned long long ) );
printf( "uint64_t             %lu\n" , sizeof( uint64_t )           );
printf( "float                %lu\n" , sizeof( float )              );
printf( "double               %lu\n" , sizeof( double )             );
printf( "long double          %lu\n" , sizeof( long double )        );
printf( "_Bool                %lu\n" , sizeof( _Bool )              );
printf( "\n" );
return 0; // Indicate successful execution of the program
}

Sample Output:

Size of C data types:
