display()

"display(); display(c

函式名:display
功能:顯示輸出函式
用法:void display();
程式例:
#includeiostream.h
template class k1, class k2
void display(k1 x, k2 y);
void main()
{
char c=h,str[]=ok2002;
int n=100;
float x=5.5;
double z=1.23456;
//兩個參數類型相同
display(c, char(c+2)); //h j
display(x,2*x); //5.5 11
display(n, 2*n); //100 200
display(str, str); //ok2002 ok2002
display(z, 2*z); //1.23456 2.46912
//兩個參數類型不同
display(c, str); //h ok2002
display(str,2*x); //ok2002 11
display(str, c); //ok2002 h
display(n, str); //100 ok2002
display(z, n); //1.23456 100
}
