C Program to print Data Type Size and Ranges

Program:

#include< stdio.h >

#include< conio.h >

#include< limits.h >

#include< float.h >

void main( )

{

            clrscr( ); // Clear the screen Contents
            printf("Integer data type:\n\tSize: %d\n\tRange: %d to %d", sizeof(int), INT_MIN, INT_MAX);

            printf("\nCharacter data type:\n\tSize: %d\n\tRange: %d to %d", sizeof(char), CHAR_MIN, CHAR_MAX);

            printf("\nFloat data type:\n\tSize: %d\n\tRange: %E to %E", sizeof(float), FLT_MIN, FLT_MAX);

            printf("\nDouble data type:\n\tSize: %d\n\tRange: %E to %E", sizeof(double), DBL_MIN, DBL_MAX);

}

Output:

Integer data type:

           Size: 2

           Range: -32768 to 32767

Character data type:

           Size: 1

           Range: -128 to 127

Float data type:

           Size: 4

           Range: 1.17549E - 38 to 3.402823E + 38

Double data type:

           Size: 8

           Range: 2.225074E - 308 to 1.797693E + 308
