读程序写出程序执行结果
#include int b=3; int fun(int *a) { b+=*a; return(b); }void main(){ int a=2,b=2;b+=fun(&a);printf(“%d\n”,b);读程序写出程序执行结果
输出结果是7.
原因：
fun(int *a)函数中使用到的是b变量是全局变量,值为3,main()函数中b+=fun(&a)中b是局部变量,值为2,因而调用函数fun(&a)结果为5,因而输出结果是7.

什么叫'int ' differs in levels of indirection from 'void *'我的程序代码如下（部分）（运行界面visual C++）：#include #include #include main(){ int number=-1;int i=0;int a=0;char b[50];char code[1000];char cache[50];char *m=&b[50]
