Write a program called asci.c that prints the ASCII codes of printable character

ID: 667023 • Letter: W

Question

Write a program called asci.c that prints the ASCII codes of printable characters, uppercase characters, lowercase characters, and of digits, depending on a command-line option. The options are:

-printable
-upper
-lower
-digit
If no option is set, then -printable is the default. It the option is incorrect, or there are too many arguments on the command line, then a usage message is output. The possible behaviours are:
prompt$ ./asci -printable
32     33 !   34 "   35 #   36 $   37 %   38 &   39 '
40 (   41 )   42 *   43 +   44 ,   45 -   46 .   47 /
48 0   49 1   50 2   51 3   52 4   53 5   54 6   55 7
56 8   57 9   58 :   59 ;   60 <   61 =   62 >   63 ?
64 @   65 A   66 B   67 C   68 D   69 E   70 F   71 G
72 H   73 I   74 J   75 K   76 L   77 M   78 N   79 O
80 P   81 Q   82 R   83 S   84 T   85 U   86 V   87 W
88 X   89 Y   90 Z   91 [   92    93 ]   94 ^   95 _
96 `   97 a   98 b   99 c   100 d   101 e   102 f   103 g
104 h   105 i   106 j   107 k   108 l   109 m   110 n   111 o
112 p   113 q   114 r   115 s   116 t   117 u   118 v   119 w
120 x   121 y   122 z   123 {   124 |   125 }   126 ~


With no option, it does printable:
prompt$ ./asci
32     33 !   34 "   35 #   36 $   37 %   38 &   39 '
40 (   41 )   42 *   43 +   44 ,   45 -   46 .   47 /
48 0   49 1   50 2   51 3   52 4   53 5   54 6   55 7
56 8   57 9   58 :   59 ;   60 <   61 =   62 >   63 ?
64 @   65 A   66 B   67 C   68 D   69 E   70 F   71 G
72 H   73 I   74 J   75 K   76 L   77 M   78 N   79 O
80 P   81 Q   82 R   83 S   84 T   85 U   86 V   87 W
88 X   89 Y   90 Z   91 [   92    93 ]   94 ^   95 _
96 `   97 a   98 b   99 c   100 d   101 e   102 f   103 g
104 h   105 i   106 j   107 k   108 l   109 m   110 n   111 o
112 p   113 q   114 r   115 s   116 t   117 u   118 v   119 w
120 x   121 y   122 z   123 {   124 |   125 }   126 ~

prompt$ ./asci -upper
65 A   66 B   67 C   68 D   69 E   70 F   71 G   72 H
73 I   74 J   75 K   76 L   77 M   78 N   79 O   80 P
81 Q   82 R   83 S   84 T   85 U   86 V   87 W   88 X
89 Y   90 Z

prompt$ ./asci -lower
97 a   98 b   99 c   100 d   101 e   102 f   103 g   104 h
105 i   106 j   107 k   108 l   109 m   110 n   111 o   112 p
113 q   114 r   115 s   116 t   117 u   118 v   119 w   120 x
121 y   122 z

prompt$ ./asci -digit
48 0   49 1   50 2   51 3   52 4   53 5   54 6   55 7
56 8   57 9

If the option is spelt incorrectly:
prompt$ ./asci -up
Usage: ./asci [-printable,-upper,-lower,-digit]

or if there are too many options:
prompt$ ./asci -upper -lower
Usage: ./asci [-printable,-upper,-lower,-digit]

Explanation / Answer

I have written the program for Upper, lower and digits

#include<stdio.h>

int main()
{
    char c;
    int i;
    printf("Enter u to display ascii for uppercase and l to display ascii for lowercase and d to display ascii for digits : ");
    scanf("%c",&c);
    if(c=='U' || c=='u')
    {
       for(c='A'; c<='Z'; ++c)
       printf("ASCII value of character %e: %d ",c,c);
   }
   else if (c=='L' || c=='l')
    {
        for(c='a'; c<='z'; ++c)
      printf("ASCII value of character %e: %d ",c,c);
   }
   else if (c==d)
         {
           for(i=0;i<=255;i++)
          printf("ASCII value of character %e: %d ",i,i);   
        }
    if (c!='U' || c!='L' || c=='u' || c=='l')
         printf("Type u or l or d");
    return 0;
}
