[Jay]

How can I cast Integer value 450 to a char[10] array "450 "? in a c program?

thanks in advance for any help.

Re: type cast from integer to char array

sprintf, sscanf

function will help you

if your environment is linux(unix), man page will give about those functions
to you.

How is sscanf going to help?

int number = 450;
char string[10];

sprintf(string, "%9d", number);

You don't. Are you sure you understand what a cast is?
It converts one type to another.

What you're really asking is how to store the textual
representation of a numeric type into an array of
characters. Use the 'sprintf()' function, which
works just like 'printf()' except its output goes
to a char array instead of stdout.

#include <stdio.h>

int main()
{
char array[10] = {0};
int i = 450;
sprintf(array, "%d", i);
printf("%s\n", array);
return 0;
}

Maybe he wants to check the result of the conversion ;-)

You're not solving the OP's problem: he wants the digits 450 followed by
7 spaces, i.e. not a string. The solution is a bit more complicated:

char array[10], buff[sizeof array + 1];
sprintf(buff, "%-10d", 450);
memcpy(array, buff, sizeof array);

Then again, maybe the OP actually wanted your solution, but didn't
formulate his question properly.

What "tailing null character"? The word "string" does not appear in OP's
request, does it?

This answers my question, thank you all for your help.

Then, your question was extremely poorly phrased (your example shows 3
digits followed by 7 spaces). BTW, there is no point in overwriting
the null character appended by the sprintf call with array[9] = '\0'.
sprintf is quite good at generating strings...
