convert int to char?

[Guest_imported]

Can you convert an int to a char???? or a long to a char?

Check if your library has the itoa() function. If it doesnt you will have to write your own version or download it from the web.

Hi

Converting an int or long to a char. If you are talking about the values themselves, if they fit the range of char (-128 to 127) you're fine just assigning them:

long lv = 100;
int iv = 100;
char cv = lv;

The compiler might complain about truncating, but that is fine, as you want to do this.

If you're talking about "converting to character string", try the sprintf() function, or better, snprintf() (may not be present on your system).

char buffer[1024];
snprintf(buffer,1024,"%ld %d\n",lv,iv);

fills the buffer with "100 100"

hai friend,
i have an idea that is
sprintf(buff,"%d",i); for int var
sprintf(buff,"%ld",l) for long var

or
itoa(); for int
ltoa() for long in "stdlib.h"
bye..

converting an "int" or "long" value to a char is pretty easy.Here is one of the way that you can use to do it:

/* for an int */
int var;
char c;
c = (char)var;

/* for a long */
long var;
char c;
c = (char)var;

why not try our own implementation!!!!
main()
{
char s[6];//int cant exceed 6
int n;
scanf("%d",&n);
conv(n,q);
strrev(q);
printf("%s",q);
}

int conv(int n,char *s)
{
if{
conv(n/10,s+1);
*s=n%10+'0';
} else *s='\0';
}

???can someone suggest a recusive version that does n't require reversing at the end

hey leibnitz....u should have tried before u submit ,it 's coming out wierd....see the sizes of char and int are by different so u cant attempt that way

 

[danielhozac]

Why should you reinvent the wheel? Just use sprintf or snprintf, which have already been mentioned above. //Daniel

hey doing things our way is more thrilling....rememeber we are programmers... suggest something better than cvrmurthy

 

[Leibnitz]

I'am sorry to say that cvrmurthy,but there is nothing weird with my code and it is the simplest way to do it.
If you are having weird results,please post your code and the weird outputs that you are getting.

Here is an example of the technic that i have sugest:

#include<stdio.h>

void main()
{
	int var = 36;
	char c;

	c = (char)var;

	printf(&quot;%c&quot;,c);
}

output: $
