C-进程已退出,错误代码为3221225477
我正在为我们的编译器设计主题做一个移位减少算法。这是代码C-进程已退出,错误代码为3221225477,c,windows,shift-reduce,C,Windows,Shift Reduce,我正在为我们的编译器设计主题做一个移位减少算法。这是代码 void shiftReduce(char str[MAX_CHAR], int prodNum, int line) { int limit = 5, y=0; int substrFlag = 1; //0 true 1 false int ctr,x, counter; int match, next; char stack[MAX_CHAR]; clearString(stack);
void shiftReduce(char str[MAX_CHAR], int prodNum, int line)
{
int limit = 5, y=0;
int substrFlag = 1; //0 true 1 false
int ctr,x, counter;
int match, next;
char stack[MAX_CHAR];
clearString(stack);
OUTER:while ((strcmp(stack, prod[0].left) != 0) && (y < limit))
{
addChar(stack, str[0]);
strcpy(str, dequeue(str));
printf("Stack = %s\nQueue = %s\n", stack, str);
for (ctr = 0; ctr < prodNum; ctr++)
{
if (strstr(stack, prod[ctr].right) != NULL)
{ //substring found
substrFlag = 0;
strcpy(stack, replace(stack, prod[ctr].right, prod[ctr].left));
goto OUTER;
}
}
if ((str[0] == '\n') || (str[0] == '\0'))
y++;
}
if (strcmp(stack, prod[0].left) == 0)
;//printf("%s - Accepted.\n", stack);
else
printf("Syntax error on line %i\n", line);
}
和addChar函数:
void addChar (char * str, char letter)
{
int a = 0;
while (str[a] != '\0')
a++;
str[a] = letter;
str[a+1] = '\0';
return;
}
最后替换函数
char * replace (char orig[MAX_CHAR], char substr[MAX_CHAR], char rep[MAX_CHAR])
{
int match, end=0, next=0;
int flag = 0; //0 true 1 false
char temp [MAX_CHAR];
char store[MAX_CHAR];
if (strstr(orig, substr) == NULL)
return NULL;
int x,y;
for (x = 0; x < length(orig); x++)
{
if (orig[x] == substr[0]) //if current character is equal to first character of substring
{
match = x;
for (y = 0; y < length(substr); y++)
{
if (orig[match+y] != substr[y])
{
flag = 1;
break;
}
}
if (flag == 0)
{
next = match + length(substr);
for (y = 0; y < length(rep); y++)
{
temp[match+y] = rep[y];
end = (match+y);
}
for (y = next; y < length(orig); y++)
{
temp[y] = orig[next+(y-next)];
}
return temp;
}
}
else
{
addChar(temp, orig[x]);
}
}
return temp;
}
当我注释printf时(“Stack=%s\nQueue=%s\n”,Stack,str)代码>行,它工作得很好。但是当我取消注释它时,它返回代码322225477
然后很可能是stack
或str
未被0
终止或指向无效内存。“…它返回代码322225477…”您是什么意思?“Returns”在编程中有相当具体的含义,但您要问的函数是void
。你的意思是它抛出了一个错误吗?322225477
是0xc000005
这是一个windows程序员非常熟悉的数字…;-)
