How to convert from int to char in SI?

Question

C++ / C#

Good afternoon. I want to display a number in putchar, but putchar only outputs string variables. How can I stringify my numeric variable?

Answer 1

To directly answer the question, then assuming that you only confused characters and strings, like this

int i=5;

putchar ('0'+i);

but I suspect that this is not what is really needed at all, tk. You probably confused more than just characters and lines.

Answer 2

putchar writes only 1 character to the output stream.
Probably what you really need is this:
printf("%d\n", i);

Answer 3

int i = 97;
char a = i;
