# C and C++ Print ASCII Values of single or all characters

In this post, we will learn C and C++ Print ASCII Values of single or all characters. The user will enter a character and will find out ASCII values of entered character. To Find out ASCII values of characters in the range loop are used. We will cover finding ASCII of character is entered by the user in C and C++, C++ programs ASCII value of string character, Find ASCII values of all characters

### 1. C Program to Find ASCII Values for all characters

The ASCII value of characters Falls in the range of 65 to 122 . Where 65 represents the upper case character A and 90 characters Z.To find out all charcater ASCII values run we have to run a loop starting for 65 till 122.

• The range from 65 to 90 is for upper case letters: A to Z.
• The range from 91 to 96 is the ASCII value of a special character
• The range from 97 to 122 is for lower case letters: a to z.

#### C Program to Find ASCII Values for all characters

```#include <stdio.h>
int main() {

int val = 0;
printf("All Character \t ASCII Value\n\n");

for (val = 65; val <=122; val++) {
printf("%c = %d\n", val, val);

}
return 0;
}

```

Output

```All 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
[ = 91
\ = 92
] = 93
^ = 94
_ = 95
` = 96
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

```

### 2. C Program to Find ASCII Values of a character entered by the user

Sometimes instead of printing the ASCII values of all letters, we have to print the letter entered by the user. In this example, we are asking the user to enter the character to find the ASCII value.

```#include <stdio.h>
int main() {
char ch;
printf("Enter a character: ");
scanf("%c", &ch);

printf("ASCII value of %c = %d", ch, ch);

return 0;
}

```

Output

```Enter a character: A
ASCII value of A = 65

```

### 3. C++ Program to Find ASCII Values for all characters

In this example, we are printing the ASCII value of the upper case letter, lower case letter, and special characters whose range starts from 65 to 122. To print all we are looping start from 65 till 122.

#### C++ Program Example

```#include <iostream>
using namespace std;
int main() {

int val = 0;
char  ch;
cout<<"The ASCII value of all charcters:\n ";

for (val = 65; val <=122; val++) {
ch = val;
cout<<ch<<" = "<<val<<endl;
}

return 0;
}

```

Output

```The ASCII value of all charcters:
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
[ = 91
\ = 92
] = 93
^ = 94
_ = 95
` = 96
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

```

### 4. C++ Program to Find ASCII Values single character entered by the user

Sometimes instead of printing the ASCII values of all letters, we have to print the letter entered by the user.In this C++ program example, we are asking the user to enter the character to find the ASCII value and finding the ASCII value of entered character printing the result.

```#include <iostream>
using namespace std;
int main() {

int val = 0;
char  ch;
cout<<"Enter the Character: ";
cin>>ch;
val = ch;
cout<<"The ASCII value of "<<ch<<"  = "<<val<<endl;

return 0;
}

```

Output

```Enter the Character: A
The ASCII value of A  = 65

```

### 5. C++ Program to Find ASCII value of all characters in a string

In this C++ program, we are asking users to enter a string value and we are iterating each character of string using a while loop and printing its character.

#### C++ Program Example

```#include <iostream>
#include <string>
using namespace std;

int main() {
string str_domain;
char ch;
int x=0, val;
getline (cin, str_domain);

cout<<"\nCharacter\t\tASCII Value\n"<<endl;
while(str_domain[x])
{
ch = str_domain[x];
val = ch;
cout<<ch<<"\t\t\t"<<val<<endl;
x++;
}

return 0;
}
```

Output

```Please Enter String: devenum.com

Character		ASCII Value

d			100
e			101
v			118
e			101
n			110
u			117
m			109
.			46
c			99
o			111
m			109

```
