You should use static_cast(i) to cast the integer i to char . reinterpret_cast should almost never be used, unless you want to cast one type into a fundamentally different type.

Can you convert int to char?

We can convert int to char in java using typecasting. To convert higher data type into lower, we need to perform typecasting. Here, the ASCII character of integer value will be stored in the char variable. Alternatively, you can use Character.

How do I convert ASCII to char in C++?

How do you convert to int?

Java int to String Example using Integer. toString()

1. public class IntToStringExample2{
2. public static void main(String args[]){
3. int i=200;
4. String s=Integer.toString(i);
5. System.out.println(i+100);//300 because + is binary plus operator.
6. System.out.println(s+100);//200100 because + is string concatenation operator.

How do you check if a number is an integer or float in C++?

Also sscanf () and sprintf () would help. Just assign the int to a char variable.

Where are integers stored in a C program?

Integers are stored in many types: int being the most popular for a balance of speed, size and range. ASCII is by far the most popular character encoding, but others exist. The ASCII code for an ‘A’ is 65, ‘a’ is 97, ‘\ ‘ is 10, etc. ASCII data is most often stored in a char variable.
