Can't run this code Visual Studio (still work in another IDE)-CodePudding

#include<iostream>
#include<vector>
using namespace std;
main() {
    int x;
    char str[80];
    cout << "Enter a number and a string:\n";
    cin >> x;
    cin.getline(str, 80); //take a string
    cout << "You have entered:\n";
    cout << x << endl;
    cout << str << endl;
}

It will show the error: There were build error https://imgur.com/jY8tYoA

I was try it on onlinegdb, it can run normally. I try create a new project in VS and put the code in but it still not worked

CodePudding user response：

That's a small problem. In C / C, we shoule always write int main().

#include<iostream>
#include<vector>
using namespace std;
int main() {
    int x;
    char str[80];
    cout << "Enter a number and a string:\n";
    cin >> x;
    cin.getline(str, 80); //take a string
    cout << "You have entered:\n";
    cout << x << endl;
    cout << str << endl;
}

This will solve the error.

And if it is in C language, we can use string instead if char[].

Try to add C plugin or code support extensions for VS code. Check on below link. https://code.visualstudio.com/docs/languages/cpp
