string::assign for int type?

[kenneth6]

name & line are string type;
age is int type.

size_t found_2=line.find("\s", found_1);    
name.assign(line,found_1,found_2);
 
size_t found_3=line.find("\s", found_2);
age.assign(line,found_2,found_3);

when i debug, msvc told me assign is a function for string only. how can i do the same job for int type?

I'm not sure what your intent is here. Are you extracting a number (as text) from the string 'line' and you want to store the value in the int 'age'?

If so you'll have to convert the substring to int first. If this is not what your intending then I need more clarification.

#include <iostream>
#include <stdlib.h>
#include <string>
using namespace std;
 
 
int main()
{
    string str1[3];
    string aray[3];
    string str1[0]={123450};
    string str1[1]={123451};
    string str1[2]={123452};
 
    for (int i=0; i<2; i++)
    {
        cout << str1[i] << endl;
    }
 
    for(int j=0; j<100; j++)
    {
        int aray[j] = atoi(str1[j].c_str());
    }
 
    for (int i=0; i<2; i++)
    {
        cout << aray[i] << endl;
    }
}

Yes, i want to do the job u said. but what you mean by convert the substring to int first ?? is that what i did in the above?
What's wrong with that code? Many errors

i solved the problem on my own !! thx u all

some definition problem in the codees...

I hope you found out that string only uses the char data type.

wstring uses wchar_t and these are the only teo types u you can use in basic_string<>.
