若有int a[4]={1,2,3,4};,则a[a[3-a[1]]]的值为

矩阵相加（C++）#include using namespace std; const int rows=3;const int cols=3;void matrixadd(int *,int *,int *,int,int);int main(){int a[rows][cols]={{1,3,5},{7,8,11},{13,15,17}};int b[rows][cols]={{9,8,7},{6,5,4},{3,2,1}};int c[rows][cols]={0 int a[3][3]={{1,2,3},{4,5,6},{7,8,9}}; int **p; p=(int**)a; 其中p=(int**)a;是什么意思啊 一个关于C语言指针的问题,源程序：#include intmain(){int a[5]={1,2,3,4,5};int *ptr1=(int *)(&a+1);int *ptr2=(int *)((int)a+1);printf(%x,%x,ptr1[-1],*ptr2);return 0;} #include int b=2; int fun(int *k) {b=*k+b;return(b);} main() {int a[10]={1,2,3,4,5,6,7,8}, 若有int a[4]={1,2,3,4};,则a[a[3-a[1]]]的值为 int a[]={1,2,3,4,2,4,5,2}; int b=LB(a,4)+LB(a+3,#includeint LB(int *a,int n) {int i,s=1;for(i=0;i int a[3][3]={{1,2,3},{4,5},{6}}; int i, Int[] a={1,2,3,4,5}; For(int count=0;count #include int b=2; int fun(int*k) { b=*k+b;return(b);} main() {int a[10]={1,2,3,4,5,6,7,8}#include int b=2; int fun(int*k) { b=*k+b;return(b);} main() {int a[10]={1,2,3,4,5,6,7,8},i;for(i=2;i void fun(int a,int b) { int t; t=a;a=b;b=t; } main()void fun(int a,int b){ int t; t=a;a=b;b=t; } main() { int c[10]={1,2,3,4,5,6,7,8,9,0}.i; for(i=0;i 若有定义：int b=7;float a=2.5,c=4.7;则下面的表达式 a+(int)(b/3*(int)(a+c)/2)%4 的值5怎么来的? 若有定义 int b=7；float a=2.5, c=4.7；则下列表达式 a+(int)(b/3*(int)(a+c)/2)%4的值为详细点 谢谢 谢谢大家 若有定义“int a=7;float x=2.5,y=4.7;”,则表达式x+a%3*(int)(x+y)%2/4的值是多 15.若有定义:int a=7;float x=2.5,y=4.7;则表达式x+a%3*(int)(x+y)%2/4的值是( ) 若有定义:int a=7;float x=2.5,y=4.7;则表达式x+a%3*(int)(x+y)%2/4的值是? 若有定义：int a=7;float x=2.5,y=4.7; ,则表达式x+a%3*(int)(x+y)%2/4的值是 若有定义 int a=7;folat x=2.5,y = 4.7; 则表达式++a%3*(int)(x+y)%2/4的值是 #define N 20 fun(int a[],int n,int m) {int i; for(i=m;i>n;i--)a[i+1]=a[i]; return m; } void main() #define N 20fun(int a[],int n,int m){int i;for(i=m;i>n;i--)a[i+1]=a[i];return m;}void main(){ int i,a[N]={1,2,3,4,5,6,7,8,9,10};fun(a,0,N/2);for(i=0;i
