error while compiling

[shivas88]

I was compiling a c++ program and it gives 2 errors:
1) expected ';' before '{' token
2) expected '}' at end of input.

But when I check the program all instructions have a ';' and i have also terminated all the functions with proper '}'

Can anyone please tell me wht are the other possibilities of mistake?

here is the function which supposedly has the first error:

int tag;

if(not_issue==1)
goto label;

If you use [code][/code] tags and indent your code you may see where the error is

I'd say that the last part shows some if/else mismatch

    else(!strcmp(instr,"SD"))
    {
        tag=50;
        if(issue_rs(store,store_rs,dest_op,src1_op,src2_op,STORECYCLE,tag,clock,sd_pr))
        {
            store_stall+=1;
            not_issue=1;
        }
    }
    return 0;
    else // to which if?
    return 1;
}
