first linux programme

[hameedkhan]

hi,
i just started programming in linux. i was trying to make the following programme but the programme didn't work as expected. i just want to know how can we print the character with ascii value 1 because the following programme isn't priniting the character with ascii value 1.

Code: Select all

#include <stdio.h>

main()
{
  printf("Ascii=%d, Character=%c\n",1,1);
}

when i try to run the above programme i got the following output.

Code: Select all

hameed@khan:~/programming/letusc$ cc asciival1.c
hameed@khan:~/programming/letusc$ ./a.out
Ascii=1, Character=
hameed@khan:~/programming/letusc$

anybody know what can i do to print or we can't print those special character in linux

Thanks,
Hameed Khan.

$: cat main.c
#include <stdio.h>

main()
{
printf("Ascii=%d,Character=%c\n",'1','1'); /* Note: Single-Quotes Around 1s */

return(0);
}

your code is correct. it is printing 1. type

Code: Select all

./a.out | od -c

The code is not correct , if he wants ascii values and character values he has to place his 1s in single quotes, which i corrected in his code,

i think you didn't understand my question. i want to print the character whose ascii value is 1. if i run the above programme in windows it will print a smiley face inplace of %c. i know in linux it will be little different.
i hope now you understand my question.

Thanks,

Ah, my mistake sorry..

Then look it up here,

Using what lamba said the octal value was 001,
thus what should have been printed out is SOH (Start of Heading)

Look under the invisibile characters section of page.
