Program to Print ASCII Value of a Character in C
ASCII Value :
On this page we will discuss about how to find the ASCII value of a character in C programming language. Each character is assigned an ASCII value. In C, characters are stored in the memory using their ASCII values.
ASCII Code:
- ASCII stands for American Standard Code for Information Interchange.
- A character encoding scheme used in communications is called ASCII.
- 256 ASCII characters are available, but we only use 128 of them (0 to 127).
- These include numbers, punctuation marks, capital and lowercase characters, and more.
- In C, a character variable holds the character’s ASCII value (instead of the character itself).
- The character variables in numbers are represented by the ASCII value.
- For instance, “A” has the ASCII value of 65.
Now lets see Program for ASCII values in C –
ASCII Value Table :
ASCII Table for Uppercase Character
| Character | ASCII Value |
|---|---|
| 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 |
ASCII Table for Lowercase Character
| Character | ASCII Value |
|---|---|
| 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 |
Example 1 :
Write a program to print ascii value of given character.
Run
#include<stdio.h>
int main ()
{
char ch;
printf ("Enter the Character = ");
scanf ("%c", &ch);
printf ("\nThe ASCII Value of %c = %d", ch, ch);
return 0;
}
Output:
Enter the Character = S The ASCII Value of S = 83
Example 2 :
Write a program to print all the ascii value of given input character.
Run
#include<stdio.h>
int main ()
{
char name[30];
int i = 0;
printf ("Enter a name = ");
scanf ("%s", name);
while (name[i] != '\0')
{
printf ("\nThe ascii value of %c = %d", name[i], name[i]);
i++;
}
return 0;
}
Output:
Enter a name = Shanvi The ascii value of S = 83 The ascii value of h = 104 The ascii value of a = 97 The ascii value of n = 110 The ascii value of v = 118 The ascii value of i = 105
Example 3:
Run
#include<stdio.h>
int main ()
{
int a = 65, b = 97;
printf ("Alphabets with their ascii value :\n");
for (int i = 0; i <= 25; i++)
{
printf ("%c : %d\n", a + i, a + i);
}
for (int i = 0; i <= 25; i++)
{
printf ("%c : %d\n", b + i, b + i);
}
return 0;
}
Output:
Alphabets with their ascii value : 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 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
