Question

c++怎么编一个应用程序？要把输入的数值换成ascall输出。

Answer 1

#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
char c;

cout << "Please input a char:" ;
cin >> c;
cout << c << "=" << (int)c;
return 0;
}
//用cout时强制转化为int类型就可以了

Answer 2

#include<iostream>
using namespace std;

int main()
{
int a;
cout<<"Please inter a number: "<<endl;
cin>>a;
cout<<"The changed number is: ";
cout<<char(a)<<endl;
return 0;
}
用这个：char(a) 强制转换就行了。

Answer 3

#include <iostream.h>
void main()
{
char a='k';
cout<<a+0<<endl;
}
