C Program To Find ASCII Value of a Character

In this post, you will get to know how to find ASCII Value of any character in the C Programming language.

ASCII Value represents the English Characters as numbers, each letter is assigned a number from 0 to 127. For example, The ASCII Value of N is 78.

So, Without Further Ado, let’s begin the tutorial.

C Program To Find ASCII Value of a Character

// C Program To Find ASCII Value of a Character
#include <stdio.h>
int main(){
    char a;
    
    // Asking for the Input
    printf("Enter the String: ");
    scanf("%c", &a);
    
    // Displays Output
    printf("ASCII Value of %c = %d", a, a);
    return 0;
}

Output

Enter the String: N
ASCII Value of N = 78

How Does This Program Work ?

char a;

In the above example, we have declared a string data type variable named a.

// Asking for the Input
    printf("Enter the String: ");
    scanf("%c", &a);

Then, the user is asked to enter a character, the character is stored in the variable a.

// Displays Output
    printf("ASCII Value of %c = %d", a, a);

Finally, the ASCII Value of the character is displayed using %d. %c is used to display the String data type.

Some Used terms as follow:

#include <stdio.h> – In the first line we have used #include, it is a preprocessor command that tells the compiler to include the contents of the stdio.h(standard input and output) file in the program.

The stdio.h is a file which contains input and output functions like scanf() and printf() to take input and display output respectively.

Int main() – Here main() is the function name and int is the return type of this function. The Execution of any Programming written in C language begins with main() function.

scanf() – scanf() function is used to take input from the user. Here %c indicates that we are reading String Data Type.

printf() – printf() function is used to display and print the string under the quotation to the screen.

C Program To Find ASCII Value of all Characters

// C Program To Print ASCII Value of all Characters
#include <stdio.h>
int main(){
    int i;
    
    for (i = 0; i < 26; i++){
        printf("%c = %d | %c = %d \n", 'A'+i, 'A'+i, 'a'+i, 'a'+i);
    }
    return 0;
}

Output

A = 65 | a = 97 
B = 66 | b = 98 
C = 67 | c = 99 
D = 68 | d = 100 
E = 69 | e = 101 
F = 70 | f = 102 
G = 71 | g = 103 
H = 72 | h = 104 
I = 73 | i = 105 
J = 74 | j = 106 
K = 75 | k = 107 
L = 76 | l = 108 
M = 77 | m = 109 
N = 78 | n = 110 
O = 79 | o = 111 
P = 80 | p = 112 
Q = 81 | q = 113 
R = 82 | r = 114 
S = 83 | s = 115 
T = 84 | t = 116 
U = 85 | u = 117 
V = 86 | v = 118 
W = 87 | w = 119 
X = 88 | x = 120 
Y = 89 | y = 121 
Z = 90 | z = 122
