此程序只需使用ASCII行文件,将其放入链接列表堆栈,然后将反转列表打印为相同ASCII格式的新文件.
我的结构代码:
typedef struct Node{
char info[15];
struct Node *ptr;
};
我在Main上遇到以下错误.大多数人都必须在我声明新节点头的地方做...那个语法出了什么问题？:
Errors
strrev.c:28: error: ‘Node’ undeclared (first use in this function)
strrev.c:28: error: (Each undeclared identifier is reported only once
strrev.c:28: error: for each function it appears in.)
strrev.c:28: error: ‘head’ undeclared (first use in this function)
strrev.c:34: warning: passing argument 1 of ‘strcpy’ from incompatible pointer type
/usr/include/string.h:128: note: expected ‘char * __restrict__’ but argument is of type ‘char **’
主要代码:
int main(int argc, char *argv[])
{

我正在尝试让我的makefile将三个c程序编译成一个可执行文件,但是我收到以下错误:
cachesim.o: could not read symbols: File in wrong format
是的,我每次使用时都会使用make clean.make文件如下
CC = gcc
CFLAGS = -Wall -m32 -O -g
all: cachesim cache trace_file_parser
gcc -o cachesim cachesim.o cache.o trace_file_parser.o
cachesim: cachesim.c
$(CC) -c -o cachesim.o cachesim.c $(CFLAGS)
cache: cache.c
$(CC) -c -o cache.o cache.c $(CFLAGS)
trace_file_parser: trace_file_parser.c
$(CC) -c -o trace_file_parser.o trace_file_parser.c $(CFLAGS)
clean:
rm -f *.o
我无法弄清楚为什么这是....
我每次都在使用make clean.
试图编译:
[katiea@mumble-15] (34)$ make clean
rm -f *.o
[katiea@mumble-15] (35)$ ls
