Answer :
Linker Error : Undefined symbol '_i'
Explanation:
extern storage class in the following declaration,
extern int i;
specifies to the compiler that the memory for i is allocated
in some other program and that address will be given to the
current program at the time of linking. But linker finds
that no other variable of name i is available in any other
program with memory space allocated for it. Hence a linker
error has occurred .

pls anyone can help me to write a code to print the values in words for any value.Example:1034 to print as "one thousand and thirty four only"
void main() { static int i; while(i<=10) (i>2)?i++:i--; printf(ā%dā, i); }
main() { signed int bit=512, i=5; for(;i;i--) { printf("%d\n", bit >> (i - (i -1))); } } a. 512, 256, 0, 0, 0 b. 256, 256, 0, 0, 0 c. 512, 512, 512, 512, 512 d. 256, 256, 256, 256, 256

Design an implement of the inputs functions for event mode
#include <stdio.h> main() { char * str = "hello"; char * ptr = str; char least = 127; while (*ptr++) least = (*ptr<least ) ?*ptr :least; printf("%d",least); }
main() { int i = 258; int *iPtr = &i; printf("%d %d", *((char*)iPtr), *((char*)iPtr+1) ); }
why array index always strats wuth zero?
