Can we convert int to char in C#?

How to typecast in C?
Typecasting in C. By Alex Allain. Typecasting is a way to make a variable of one type, such as an int, act like another type, such as a char, for one single operation. To typecast something, simply put the type of variable you want the actual variable to act as inside parentheses in front of the actual variable. (char)a will make ‘a’ function as a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of char s, or an array of strings. It is a pointer to a pointer, so yes, in a way it’s a 2D character array.
