此段错误是因为您缺少while周围的括号.您将继续打印测试1"，直到strsep返回NULL，然后尝试打印该结果(和段错误).

The segfault is because you're missing braces around your while. You'll keep printing "Test 1" until strsep returns NULL, then you try to print that result (and segfault).

带有几个警告标记(可能是-Wall)，gcc可以在这里提供帮助:

With several warning flags (probably -Wall), gcc helps out here:

sep.c:13:3: warning: this ‘while’ clause does not guard... [-Wmisleading-indentation]
   while((found =  strsep(&cp,"/,-")) != NULL )
   ^~~~~
sep.c:15:5: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the ‘while’
     printf("%s\n",found);
     ^~~~~~

在while周围添加花括号，该程序将按预期工作:

With braces added around the while, the program works as expected:

./sep 

Enter string: abc/def
Original string: 'abc/def'
Test 1abc
Test 1def
