简答题
16:类的静态成员和非静态成员有何区别?
17:Consider the following code:
#include
#include
int main(int argc, char *argv[]) {
int i = 1;
char buf[4];
strcpy(buf, "AAAA");
printf("%d ", i);
return 0;
}
a) When compiled and executed on x86, why does this program usually not output what the programmer intended?
b) Name several ways in which the security problem that causes this program not to output what the programmer intended can be prevented WITHOUT changing the code.
18:#include
void main()
{ int a[5] ={2,4,6,9,12},b[6] ={2,3,4,6,8,9};
for(int i=0;i<5;i++)
for(int j=0;j<6;j++)
if(*(a+i)==*(b+j) printf( ″ %d ″ ,*(a+i));
printf( ″ n ″ );
} 输出结果： _______
