enter a decimal number and give me a ASCII character upto 127?

[danishzaidi]

#include <stdio.h>
#include <conio.h>

void main()
{
int x;
printf("Enter a decimal number\n",x);
printf("The character is %c\n",x);
getch ();
}

whats wrong with it.it does not give any ascii code.please tell me simple program.

Are you familiar with the concept of a manual? If not, I suggest you look it up. Here, straight from the printf manual, headed under 'conversion specifier', 'c':

... the int argument is converted to an unsigned char, and the resulting character is written.

#include <stdio.h>

void main()
{
int x;
printf("Enter a decimal number\n",x);
printf("The character is %c\n",x);
getch ();
}

What decimal numbers are you entering? try 65 which should print A or 49 which should print 1

Look at an ASCII code chart... *not all decimal values lead to printable characters!*

For example if you entered 7 ... your computer should beep at you (ascii bell character)

The ASCII code was originally created to standardize communications between teletype stations on the old "Telegram" network... It thus includes a number of control characters such as Carriage Return, End of Page, Line Feed, etc. that were used to control the mechanism itself.

my above program is returning me the same value every time.it prints unknown character every time and on each value i give.whats wrong with my program?

Well first of all you're not asking for input anywhere...

#include <stdio.h>
#include <conio.h>

void main()
{
int x = 0;
printf("Enter a decimal number\n",x);  // this does not read the keyboard


// get number from user here...


printf("The character is %c\n",x);
getch ();
}

scanf("%d",&x);
if (x<=127)
ch='x' + '0';
printf("The character is %c\n",ch);

getch ();
}

see this program!

Lose lines 10 and 11 ...
in line 12... print x, not ch;

As it is... the character printed will not accurately represent the value entered.

ok thanks.done.

Printing an int with %c is wrong and probably wont work on a big-endian machine. It really should be casted to char first.
