Re: output unexpected

i write
void main()

int j;
j - = 0;
printf("%d",y);
}
& i got the answer as 842.

I got several diagnostic messages from my compiler, which refused to produce
an executable program:

gcc -W -Wall -ansi -pedantic -Wformat-nonliteral -Wcast-align
-Wpointer-arith -Wbad-function-cast -Wmissing-prototypes
-Wstrict-prototypes -Wmissing-declarations -Winline -Wundef
-Wnested-externs -Wcast-qual -Wshadow -Wconversion -Wwrite-strings
-Wno-conversion -ffloat-store -O2 -g -pg -c -o foo.o foo.c
foo.c:2: warning: function declaration isn't a prototype
foo.c:2: warning: return type of `main' is not `int'
foo.c: In function `main':
foo.c:4: parse error before `='
foo.c:5: warning: implicit declaration of function `printf'
foo.c:5: `y' undeclared (first use in this function)
foo.c:5: (Each undeclared identifier is reported only once
foo.c:5: for each function it appears in.)
make: *** [foo.o] Error 1

i tried it on various computers but the
answer is same.

I'm surprised you got any compiler to produce an executable program.

pls help me
how is this answer is?

What answer were you expecting it to produce, and why?
