Question

我想编写一个关于ascii的程序，它会给你char，并要求你输入小数，它只能选择字符或全部。有很多错误，我不知道如何解决它们。请帮我。

#include <iostream>
#include <cstdlib>
#include <ctime>

using namespace std;

void ALL();
void character();
void ask();

int main(){
ask();
return 0;
}

void ask(){

    char type;
    char character;
    char all;
    cout<<"You can choose all or only character\ttype in(all / character)"<<endl;
    cin>>type;
    do{
if(type=='character'){
    character();
}else if(type=='all'){
    ALL();
}else{
    ask();
}
}while(1);
}

void ALL(){
int a, b;   
do{
    srand((unsigned)time(NULL));
    a=rand() %255 + 1;
    b=a;
    cout<<"What is the ascii code of "<<(char) a<<" ?"<<endl;
    cin>>b;
    if(b==a){
        cout<<"You are RIGHT!!!"<<endl;
        cout<<"----------------------------------\n----------------------------------"<<endl;
    }else{
        cout<<"You are WRONG!!!"<<endl;
        cout<<"The ascii code of "<<(char) a<<" is "<<a<<endl;
        cout<<"----------------------------------\n----------------------------------"<<endl;
    }
}while(1);

}

void character(){
    int a, b, c;    
do{
    srand((unsigned)time(NULL));
    c = rand() % 2;
    if(c==1){
        b = rand() % 26 + 65;
    }else if(c==2){
        b = rand() % 26 + 97;
    }

    b=a;
    cout<<"What is the ascii code of "<<(char) a<<" ?"<<endl;
    cin>>b;
    if(b==a){
        cout<<"You are RIGHT!!!"<<endl;
        cout<<"----------------------------------\n----------------------------------"<<endl;
    }else{
        cout<<"You are WRONG!!!"<<endl;
        cout<<"The ascii code of "<<(char) a<<" is "<<a<<endl;
        cout<<"----------------------------------\n----------------------------------"<<endl;
    }
}while(1);

}

Answer 1

将char type;更改为string type; ..

此外，在您要比较type == 'character'的区域，您必须将其更改为

if(type == "character")
{
  ...
}

同样改变其他比较。

OR

如果你只想在这里使用char ......

输入c或a

并将条件更改为

if(type == 'c')
{
 ...
}

任何人都可以帮助我这个c ++程序有一些错误
