Find the ASCII value of a character

Problem Statement: Given a character, Find the ASCII value of the character.

Examples:

Example 1:
Input: c = ‘A’
Output: 65
Explanation: ASCII value of A is 65

Example 2:
Input: c = ‘e’
Output: 101
Explanation: ASCII value of e is 101

Solution

Disclaimer: Don’t jump directly to the solution, try it out yourself first.

Approach:

Basically, we store the character value in an integer which gives us the ASCII value of the character.
When we put character value inside an integer the typecasting occurs which converts character value into integer which is ASCII value.
And then we print the ASCII value.

Code:

C++ Code

#include <bits/stdc++.h>

using namespace std;

class ASCII {

  public:

    void value() {

      char c = 'A';
      cout << "The ASCII value of " << c << " is " << int(c);
    }
};
int main() {

  ASCII p1;
  p1.value();

  return 0;
}

Output:

The ASCII value of A is 65

Time Complexity: O(1)

Space Complexity: O(1)

Java Code

class Solution {

  public static void value() {

    char c = 'e';
    int ascii = c;
    System.out.println("The ASCII value of " + c + " is: " + ascii);
  }
  public static void main(String args[]) {

    value();
  }
}

Output:

The ASCII value of e is: 101

Time Complexity: O(1)

Space Complexity: O(1)
