string and integer concatenation

[powerb23]

How would i concatenate strings and integers.
For example

char* m = "there are ";
char* n = " days"
int x = 3;

i would like something like
char* ans = "there are 3 days"

Your help will be appreciated

#include <stdio.h>

int main(void)
{
   char m[] = "there are ";
   char n[] = " days";
   int x = 3;
   char ans[sizeof m + sizeof n + /*let's say*/12];
   [b]sprintf[/b](ans, "%s%d%s", m, x, n);
   puts(ans);
   return 0;
}

/* my output
there are 3 days
*/
