why does the code gets run anyway and ignores the if condition in main

[sterile bolt]

{
   cout << "would you like to turn on a numbers function? (y/n): ";
   string numtrigger;
   cin >> numtrigger;

   if (numtrigger == "y" || "yes")
        {
        int n1, n2;
        cout << "determine a beginning and ending numbers: ";cin>>n1>>n2;

    while(n1 > n2 || !cin)
    {
        cout<<"invalid input or you can't really have the first number higher try again: ";cin>>n1>>n2;
    }
    numberinbetween(n1, n2);
        }
    }

so i have an if and even when the condition is false the code runs anyway, why?

numtrigger == "y" || "yes" is not doing what you think its doing

;compile

#include <iostream>
int main()
{
int num = 1;
if (num == 0 || 2)
    std::cout << "wtf" << std::endl;
return 0;
}

Program Output

wtf

Disservin#0450 | 71ms | c++ | x86-64 gcc 12.2 | godbolt.org

[limpid steppe]

the number is not 0 and not 2

but wtf is printed

thats because it isnt evaluated as num == 0 or num == 2 but as num == 0 or 2

2 is true and so this if statement is true too

@limpid steppe so what do i put instead

[limpid steppe]

well what i said

in my example it would be

num == 0 || num == 2

ohh didn't see that

yeah

!solved
