cout<<\ cout< #include using namespace std; int main() {int j;

string ch=\ cout<<\ j=0;

while (j<=ch.size())

string ch=\ cout<<\ j=0;

while (j<=ch.size())

{ if ((ch[j]>='A') && (ch[j]<='Z')) ch[j]=155-ch[j];

cout<<\ cout<

#include #include using namespace std; int main()

{char s1[80],s2[40]; int i=0,j=0;

cout<<\ cin>>s1;

cout<<\ cin>>s2;

while (s1[i]!='\\0') i++;

while(s2[j]!='\\0') s1[i++]=s2[j++]; s1[i]='\\0';

cout<<\ return 0; }

5.13另一解

#include using namespace std; int main()

{char s1[80],s2[40];

cout<<\ cin>>s1;

cout<<\ cin>>s2; strcat(s1,s2);

cout<<\ return 0; }

5.13另一解

#include #include using namespace std; int main()

.

.

{ string s1=\ cout<<\ cout<<\ s1=s1+s2;

cout<<\ return 0; }

5.14题

#include #include using namespace std; int main()

{ const int n=5; int i,j;

string str[n],temp;

cout<<\ for(i=0;i>str[i]; for(i=0;istr[j+1]) {temp=str[j];str[j]=str[j+1];str[j+1]=temp;} cout<

5.15题

#include #include using namespace std; int main()

{ const int n=5; string str;

for(int i=0;i

{cout<<\ cin>>str; if(str[0]=='A') cout<

5.16题

#include using namespace std; int main() { const n=10; int i;

char a[n],temp;

cout<<\ for(i=0;i>a[i]; for(i=0;i

{temp=a[i];a[i]=a[n-i-1];a[n-i-1]=temp;} for(i=0;i

5.16题另一解 #include #include using namespace std; int main() { string a; int i,n; char temp;

cout<<\ cin>>a; n=a.size();

for(i=0;i

{temp=a[i];a[i]=a[n-i-1];a[n-i-1]=temp;} cout<
