断言的应用
1 #include <stdio.h>
2 //disable the assert function if "NDEBUG" defined
3 //#define NDEBUG
4 #include <assert.h>
5
6 void print_number(int* myInt) {
7 assert (myInt!=NULL);
8 printf ("%d\n",*myInt);
9 }
10
11 int main (int argc, char* argv[])
12 {
13 int a=10;
14 int * b = NULL;
15 int * c = NULL;
16
17 b=&a;
18 //comment this line to generate an assert
19 //c=&argc;
20
21 print_number (b);
22 print_number (c);
23
24 return 0;
25 }
输出结果举例:
10
Assertion failed: myInt!=NULL, file
C:\_Tasks\_VC6.0\Temp\Hello.cpp, line 7
