Question

Its a pretty old question. I want to insert an integer in a character array.
Eg:

int a=10;
char c[100];

EDIT: Suppose I have a character array “char c[20];”. I want to put numbers in the array.
Like:

c[0]='1'; 
c[1]='9'; 
c[2]='x';

on printing the output should be ’19x’;

PS: I don’t want ascii equivalent of integers to be inserted in array.

Answer 1

In Java you can use a StringBuilder as your character array

StringBuilder sb = new StringBuilder();
sb.append(10); // add "10" as text.

If you want just a string with the number you can use

String c = Integer.toString(10);

or

String c = "" + 10;

e.g.

String c = "before " + a + " after";
