#include<iostream>
using namespace std;
int main()
{
char c1 = 'a', c2 = 'b', c3 = 'c', c4 = '\101', c5 = '\116';
cout << c1 << c2 << c3 << '\n';
cout << "\t\b" << c4 << '\t' << c5 << '\n';
return 0;
}

 结果：

4.

#include<iostream>
using namespace std;
int main()
{
char c1 = 'C', c2 = '+', c3 = '+';
cout << "I say: \"" << c1 << c2 << c3 << '\"';
cout << "\t\t" << "He says: \"C++ is very interesting!\"" << '\n';
return 0;
}

 结果：

#include<iostream>
using namespace std;
int main()
{
int i, j, m, n;
i = 8;
j = 10;
m = ++i + j++;
n = (++i) + (++j) + m;
cout << i << '\t' << j << '\t' << m << '\t' << n << endl;
return 0;
}

 结果：

 8.

#include<iostream>
using namespace std;
int main()
{
char c1 = 'C', c2 = 'h', c3 = 'i', c4 = 'n', c5 = 'a';
int n = 4;
c1 = c1 + n;
c2 = c2 + n;
c3 = c3 + n;
c4 = c4 + n;
c5 = c5 + n;
cout << c1 << c2 << c3 << c4 << c5 << endl;
return 0;
}

 结果：
