Question

In C, write a program to convert a char (0-9) to Dec (ASCII value). Then convert an ASCII Value to char

-------+ | ASCII CODE | + - ---+ +-- | char | Dec | ----+ | 'O' => 48 | | '1' => 49 | '2' => 50 | '3' => 51 | | '4' => 52 | | '5' => 53 | '6' => 54 | | '7' => 55 | | '8' => 56 | | '9' => 571 + -------------+ then reads a character (0 - 9), and displays the corresponding decimal ASCII value e.g. if the user enters 4, this message should appear "The selected character's ASCII code is 52". After that, the program displays the following table: +-- -----+ | ASCII CODE | +-- --+ | Dec | char | +- ---+ | 48 => '0' 1 49 => '1' | | 50 => '2' | | 51 => '3' | 52 => '4' | | 53 => '5' | 54 => '6' 1 155 => '7' 1 156 => '8' 1 1 57 => '9' | + -------------+ then reads an integer number (48-57), and displays the corresponding character e.g. if the user enters 55, this message should appear "The selected character is '7'". Please note the single quotes arou Note: Do not use if, if-else, if-elseif, ternary operator, switch-case or any other decision structures to solve this problem. If the program contains any of these structures its grade will be zero.

Answer 1

#include <stdio.h>
int main()
{
char aa;
int ba;
   int i;
   int j;
   char bb;
   printf("+------------+\n");
   printf("| ASCII CODE |\n");
   printf("+------------+\n");
   printf("| char | Dec |\n");
   printf("+------------+\n");
   for(i=0,j=48;i<10;i++,j++)
       printf("| '%c' => %d |\n",i+48,j);
   printf("+------------+\n");
scanf("%d",&aa);
int ab;
ab=aa+'0';
printf("The selected character's ASCII code is %d\n",ab);
printf("+------------+\n");
   printf("| ASCII CODE |\n");
   printf("+------------+\n");
   printf("| Dec | char |\n");
   printf("+------------+\n");
   for(i=0,j=48;i<10;i++,j++)
       printf("| %d => '%c' |\n",j,i+48);
   printf("+------------+\n");
scanf("%d",&ba);
bb=ba-48;
printf("The selected character is '%d'",bb);
return 0;
}

OUTPUT:

I ASCII CODE I char i Deci ------------- ܘܝܙܝܬܢܝ ܩܩܗ ܨܢ ܗܩ - --- =y The selected character's ASCII code is 52 I ASCII CODE I Dec 1 char : ܘܚܙܢ݈ܬ ܝ ܣܩܗܪܸܢ ܗ ܟ̣ 55 The selected character is '?'
