Printing Ascii Codes as Characters Alphabets & Digits

Printing uppercase alphabets, lowercase alphabets, digits by printing them as characters typecasted from its integer form ascii values.

Learning Objectives

  • Understanding ASCII code values of different Alphabets and Numbers
  • Typecasting from numbers to characters.

Source Code

TC++ #3512

Source Code

Run Output

-- Uppercase characters with their ASCII codes --
A=65 B=66 C=67 D=68 E=69 F=70 G=71 H=72 I=73 J=74 K=75 L=76 M=77 N=78 O=79 P=80 Q=81 R=82 S=83 T=84 U=85 V=86 W=87 X=88 Y=89 Z=90
-- Lowercase characters with their ASCII codes --
a=97 b=98 c=99 d=100 e=101 f=102 g=103 h=104 i=105 j=106 k=107 l=108 m=109 n=110 o=111 p=112 q=113 r=114 s=115 t=116 u=117 v=118 w=119 x=120 y=121 z=122
-- Digits 0 to 9 with their ASCII codes --
0=48 1=49 2=50 3=51 4=52 5=53 6=54 7=55 8=56 9=57

Code Understanding

System.out.println(“– Uppercase characters with their ASCII codes –“);
for(int i=65;i<=90;++i) System.out.print(((char)i)+”=”+i+” “);
Prints character symbols of ASCII codes from 65 to 90 which are A – Z

System.out.println(“n– Lowercase characters with their ASCII codes –“);
for(int i=97;i<=122;++i) System.out.print(((char)i)+”=”+i+” “);
Prints character symbols of ASCII codes from 97 to 122 which are a – z

System.out.println(“n– Digits 0 to 9 with their ASCII codes –“);
for(int i=48;i<=57;++i) System.out.print(((char)i)+”=”+i+” “);
Prints character symbols of ASCII codes from 48 to 57 which are 0 – 9

 

Notes

  • ASCII codes from 32 to 126 are displayable characters.
  • The lowercase ascii equivalent can always be obtained by adding 32 to uppercase alphabets and vice-versa is also true.
