int main(){Intx=1,a=1;Do{ a+a+1; } While(x); Return 0;} 则语句­a=a+1执行的次数是 .A．0 B.1 C.无限次 D.有限次

这样main函数中m的值经过k=wr(m);应该为2啊 怎么显示结果还是1啊 求教#includeusingnamespacestd;int wr(int a){a++;return a;}int ty(int b){intx,y;x=b+1;y=b+2;return y;}int main(){int m,k;m=1;k=wr(m);cout int main(){Intx=1,a=1;Do{ a+a+1; } While(x); Return 0;} 则语句­a=a+1执行的次数是 .A．0 B.1 C.无限次 D.有限次 #include func(int a,int b){int c; c=a+b;returnc;}main(){intX=6,r;r#include func(int a,int b){int c; c=a+b;returnc;}main(){int x= 6,r;r = func (x,x+=2);printf (%d ,r);}A.14 B.15 C.16 D.17 intx=3;if(1 main() { int a; for(a=1;a C语言~补充完整以下程序,使其可以计算从a到b之间所有整数的和（a、b 均为从键盘输入的整数）.#include long add2n(int a,int b){intt;t=a>b?b:a;b=a>b?a:b;a=t;_____________________________________________}main(){intx,n1,n #include main() {intx=1,y=0,a=0,b=0; switch(x) { case0:a++;break; case1:b++;break; }}case2:a++;b++;break;case3:a++;b++;}printf(a=%d,b=%d/n,a,b);} main(){ int i=1;while (i void main() {int t=1;fun(fun(t));} fun(int h) {stvoid main(){int t=1;fun(fun(t));}fun(int h){static int a[3]={1,2,3}; int k; for(k=0;k error C2065:'a' :undeclared identifier#includeint main(){int print_shang();int print_xia();print_shang();print_xia();return 0;}int print_shang(){int a,b;for(a=1;a 下面语句错误的是（要详细分析的哦）A.int a=5;intx[a];B.const int a=5;int x[a];C.int n=5;int *p=new int[a];D.const int n=5;int *p=new int [a]; main() {int m[10],a;for(a=0,a 以下数组定义中错误的是（）A int x[][3]={0 }；B intx [2][3]={{1,23,4,5,6};A答案第二个没有省略啊 int f() { static int i=0; int s=1; s+=i; i++; return s; }main() { int i,a=0; for(i=0;i main() {int t=1;fun(fun(t));} fun(int h){static int a[3]={1,2,3};int k; for(k=0;k c++求2+22+222+2222+22222.#includevoid main(){int sum=0;int a=2;int n;coutn;for(int i=1;i #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}, main() { int a,b,c; a=1;b=2;c=3; if(a
