I want to print 5 characters by loop but it doesn't work.
Could anyone help me please!
or it is bug of pelles c?
#include<stdio.h>
int main(void)
{
int i;
char k;
for(i=1;i<=5;i++)
{
printf("Enter Character: ");
scanf("%c",&k);
printf("<%c> \n",k);
}
return 0;
}
output
Enter character: a
<a>
Enter character: < <== I didn't key
>
Enter character: b
<b>
Enter character: < <== I didn't key
>
Enter character: c
<c>
Press any key to continue...
Try...
scanf(" %c", &k);
printf("<%c> %d\n", k, k);
... and think again format string.
Thank you for your reply.
But I need only one character.(no space)
I used "%s" instead of "%c" It work!
But how about "%c" problem?
"%c"
No problem with Turbo C
Read least this (http://stackoverflow.com/questions/7166197/why-does-a-space-in-my-scanf-statement-make-a-difference)
For scanf() even the <Enter> pressed after the character is a valid input. That's why you got:
Enter character: a
<a>
Enter character: < <== This is the CR of <ENTER>

Quote"%c" No problem with Turbo C
It is TurboC that has a problem! The
behavior above is common to all current compilers and compliant with standards. TurboC is preAnsi and
not compliant.
The solution proposed by Timo is from the stndard. A space in format string will consume any whitespace in between (includind '\n') if present any. Following Timo suggestion scanf() will remove any space or '\n' before the char you want read.
Thank you so much for all reply.
I thought It should be the same as "%i" and "%f" for number.
