cant store more than one character on char..like if i put 'p' in henry.role it works but i-CodePudding

code:

#include <iostream>
using namespace std;

struct employee{
    
    int id;
    char role;
    float salary;
};


int main(){

    struct employee henry;



    henry.id= 101;
    henry.role= 'programmer';
    henry.salary=1200000;

    cout<<henry.role;

    return 0;
}

output:

01pr.cpp:89:17: warning: character constant too long for its type
     henry.role= 'programmer';
                 ^~~~~~~~~~~~
01pr.cpp: In function 'int main()':
01pr.cpp:89:17: warning: overflow in conversion from 'int' to 'char' changes value from '1835885938' to ''r'' [-Woverflow]

CodePudding user response：

Of course you cannot, you should declare role like string role; to assign it a string since "programmer" is a string not a single character.

CodePudding user response：

In your given example, the data member role is of type char.

You can/should solve this problem by making the role data member to be of type std::string as shown below:

#include <iostream>
#include <string>


struct employee{
    
    int id;
    std::string role; //role is of type std::string
    float salary;
};


int main(){

    struct employee henry;



    henry.id= 101;
    henry.role= "programmer"; //note the double quotes here instead of single quotes
    henry.salary=1200000;

    std::cout<<henry.role;

    return 0;
}

The output of the program is:

programmer

which can be seen here.
