写出程序分析程序写出结果

1、写生程序分析程序写生结果五、程序(26)(一).写出下列程序的输出结果是(5X2)1 . #include using namespace std; int main( ) int i=1,sum=0; do sum += i; i+;while(icoutsum=5050 2. #includeusing namespace std; int main( ) char str1 = I love china! ,str220,*p1,*p2;p1=str1;p2=str2;for(;*p1!=?0?;p1+,p2+) *p2=*p1; *p2=?0?;p1=str1;p2=str2; cou

2、tstr1= " I love china! ” str2= " I love china! ” #include using namespace std; int main()char c1=' a ' ,c2= ' d ' ,c3= ' f ' ; c1+=2; c2+=2; c3+=2;cout运行结果：cfh2. 写出下列程序的输出结果。#include using namespace std;int i,j,m,n; int main() i=5; j=6; m=+i+j+; n=(+i)+(+j)+m; cout运

3、行结果：7 8 123. 写出下列程序的输出结果。#include using namespace std; int main() const int n=5;int an=9,6,3,4,5,i,t;for(i=0;i27t=ai;ai=an-i-1;an-i-1=t; for(i=0;icout运行结果：5 4 3 6 91 . struct abc int a, b, c; ; main() struct abc s2=1,2,3,4,5,6; int t;cout36 2.void swap(int *p1,int *p2) int *p;p=p1;p1=p2;p2=p; main()

4、 int a=3,b=5; int *pt1,*pt2; pt1=&a; pt2=&b;coutcout3.53.5#include int t() static int i=100; i+=5; return i; 运行结果:i=105 i=1002、#include void swap1(int *p1, int *p2) int t;t=*p1;*p1=*p2;*p2=t; void swap2(int &p1, int &p2) int *t; t=p1;p1=p2;p2=t; void main(void) int x,y; int a,b; x=10

5、,y=20; swap1(&x,&y);a=100,b=200;void main() coutswap2(a,b);cout 运行结果是：x=20,y=10i=110#include void main(void ) int i, x,num; cin>>x; while(x) num=x%10; cout若输入x为145734则输出为：437541coutcoutsum=fun(r1,r2);couta=100,b=2001 、#include int t() static int i=100; i+=5; return i; void main() cout运

6、行结果：i=105 3#include struct s int m;float x; ;void swap(s s1, s s2) s t; t=s1; s1=s2; s2=t; s fun(s s1, s s2) s t;t.m=s1.m+s2.m; t.x=s1.x+s2.x; return t; void main() s r1=100,250.5,r2=200,350.5; swap(r1,r2);执行程序后输出：r1.m=100 r1.x=250.5 r2.m=200 r2.x= 350.5 sum.m=300sum.x=6014 、 # includeiostream.hvoid

7、 main() static char a=Radio&TV University;static intb8=6,8,9,2; char *p=a; int *q; q=b; coutcoutcout执行程序后输出：a,R,T,d0,10,8,81 #include using namespace std; int main() char c1= ' A ' ,c2= ' D ' ,c3= ' k ' ; c1+=2; c2+=3;c3-=4;coutC Gg2 . #include using namespace std; int ma

8、in() j=i/100;m=i%10;n=(i%100)/10;if(i=j*j*j+m*m*m+n*n*n) cout不是水仙花数3 #include using namespace std; int main() const int n=9;int an=9,6,3,4,5, 45, 32, 78, 21,i,t; for(i=0;it=ai;ai=an-i-1;an-i-1=t; for(i=0;icout 输出结果是：21 78 32 45 5 4 3 6 94有如下程序:#include using namespace std; class A public: A() cout)；

9、class B public: B() cout)；class C : public A B b;public:C( ) coutint main( ) C obj;return 0; 执行后的输出结果是：ABC5 . # include using namespacestd; void swap(int *p1,int *p2) int *p;p=p1;p1=p2; p2=p; main() int a=3,b=5; int *pt1,*pt2;pt1=&a; pt2=&b;coutcout运行结果：3, 53 , 56.#include #include using nam

10、espace std; int main( ) cout.fill("*"); cout.width(6); cout.f川("#"); coutreturn 0; 运行结果：#1233 . #include using namespace std; int age(int); int main() coutint age(int n) int c; if(n= =1)c=8;elsec=age(n-1)+2; return (c); 运行结果：12 4 . #include using namespace std; int main() int a5=

11、3,5,7,9,6;int i,*p=a;for(p=a;pcoutcout运行结果:1 、#includeusing namespace std;int main() float add(float,float); float a=12.68,b=56.45;c=add(a,b);coutfloat add(float x,float y) float z;z=x+y;return (z);)运行结果sum=69.13:2、#includeusing namespace std;int age(int);int main( ) coutreturn 0;int age(int n) int

12、c;if(n= =1) c=8;else c=age(n-1)+2;return (c);)运行结果：123、#includeusing namespace std;int main( ) int a5=3,5,7,9,6);int i,*p=a;for(p=a;pcoutcout)运行结果：3 5 7 return 0; void fun(int i, int j) int x=7; cout1 . #include using namespace std;int main()void fun(int,int);int i=2,x=5,j=7;fun(j,6); cout输出结果是：7 6
