Code
#include<stdio.h>
int main()
{
int i;
printf("%d \n",'\1');
printf("%d \n",'\022');
printf("%d ",'\555');
return 0;
}
Output:

When we compile this program then gcc compiler gives warning ‘\555’ is octal escape sequence out of range? What is this range?
The upper limit is usually 255, which is
'\377'. This assumes an eight-bit char type, which is not guaranteed by C, but is a safe assumption in most environments.
