二、把下列各程序运行时各输出行写到答卷相应位置处或相应横线上。(按输出行计分)
1. #include <iostream.h>
void main()
{ char *ps="wdka345aakk89gddxky";
int a=0,b=0,c=0,d=0;
for(;*ps;ps++)
switch(*ps)
{ case ‘a’:a++; break;
case ‘d’:b++; break;
case ‘k’:c++; break;
default: d++;
}
cout<< a <<","<<b<<","<<c<<","<<d<<endl;
}
输出结果为:
2. #include <iostream.h>
void main()
{ char c1,c2;
c1=‘A’+‘4’-‘2’; c2=‘a’-‘2’ +‘6’;
cout<<c1<<”,”<<c2<<endl;
}
输出结果为:
3. #include <iostream.h>
void main()
{ int i,j,k=0,m=0;
for(i=0;i<3;i++)
{ for(j=0;j<3;j++)k++,k-=j; }
m=i+j;
cout<<"k="<<k<<",m="<<m<<endl;
}
输出结果为:

1.
3，3，4，9

2.
C,e

3.
k=0,m=6

1.<3，3，4，9>
2.<C,e>
3.<k=0,m=6>
还问吗？运行下不就可以了吗？？？？？？？？？？

1. #include <iostream.h>
void main()
{ char *ps="wdka345aakk89gddxky";
int a=0,b=0,c=0,d=0;
for(;*ps;ps++)
switch(*ps)
{ case ‘a’:a++; break;
case ‘d’:b++; break;
case ‘k’:c++; break;
default: d++;
}
cout<< a <<","<<b<<","<<c<<","<<d<<endl;
}
输出结果为:
3，3，4，9

2. #include <iostream.h>
void main()
{ char c1,c2;
c1=‘A’+‘4’-‘2’; c2=‘a’-‘2’ +‘6’;

输出结果为:
