C Exercises: Create an extended ASCII table. Print the ASCII values 32 through 255

C Basic Declarations and Expressions: Exercise-88 with Solution

Write a C program to create an extended ASCII table. Print the ASCII values 32 through 255.

Sample Solution:

C Code:

#include <stdio.h>

int main( void )
{
unsigned char char1 , char2 , char3 , char4 , char5 , char6 , char7 , char8 ;

  // Print table header
printf("|---------------------------------------------------------------------------------------------------------|\n" );
printf("|extended ASCII table - excluding control characters                                                      |\n" );
printf("|   Ch Dec  Hex  |  Ch Dec  Hex   | Ch Dec  Hex | Ch Dec  Hex  | Ch Dec  Hex  | Ch Dec  Hex | Ch Dec  Hex |\n" );
printf("|----------------|----------------|-------------|--------------|--------------|-------------|-------------|\n" );

  // Loop through characters
for(int i = 0 ; i< 32; i++)
  {
    // Calculate characters for different ranges
    char1 = i;
    char2 = i+32;
    char3 = i+64;
    char4 = i+96;
    char5 = i+128; // extended ASCII characters
    char6 = i+160;
    char7 = i+192;
    char8 = i+224;

    // Print characters and their decimal and hexadecimal representations
printf( "|  %c %3d %#x " , char2 , char2 , char2 );
printf( "|  %c %3d %#x " , char3 , char3 , char3 );

    // Special case for DEL character
if( char4 == 127 ) {
printf("|%s %3d %#x |" , "DEL" , char4 , char4  );
    } else {
printf("|  %c %3d %#x |" , char4 , char4 , char4  );
    }

    // Print extended ASCII characters for current system.
printf("  %c %3d %#x |  %c %3d %#x |  %c %3d %#x |  %c %3d %#x |\n" ,
char5 , char5 , char5 ,
char6 , char6 , char6 ,
char7 , char7 , char7 ,
char8 , char8 , char8  );
  }

return 0; // Indicate successful execution of the program
}

Sample Output:

|---------------------------------------------------------------------------------------------------------|
|extended ASCII table - excluding control characters                                                      |
