将int值添加到C中的char数组

Question

I would like to add an int value in a char array. meaning if I have a 1 , I would like to represent it like '1' .

I have seen an equation to do this before to get the ASCII code of it. am working with a limited compiler for C so I don't have the luxury to use functions like sprintf() or others. it has to be in the form of an equation that I must implement. Can anybody help me with that.

example of what I'd like to do

char array[2];
char array[0] = 1 * (equation);

and then array[0] should have the value '1'.

Answer 1

If you're working with values in range 0-9, you can use

array[0] = 1 + '0';

This will give you the char representation ( '1' )of int values ( 1 ).

Answer 2

One way is to add ASCII value of 0 to the already present number.

Suppose int t=8; then we can convert t to char as follows

int t=8;

char s= t + 48; //ASCII value of '0'

So your equation should be

char s= integer + 48 ;
