What mistake i am doing in this code.

Question

#include <iostream>
using namespace std;

int main()
{
int mark = 90;

if (mark < 50) {
cout << "You failed." << endl;
}
else {
cout << "You passed." << endl;
}

if(mark=100){

cout <<"you are perfect";

}

return 0;
}

Answer 1

if(mark == 100)

mark = 100 --> mark gets the value 100
mark == 100 --> using boolean operator to compare 100 with the value of mark.
Is equal return true else return false

Answer 4

There's a mistake on your last if statement.
You wrote "if (mark=100)". The problem is that you're not doing a comparison. To compare two values, you need to use "=="
Here, you're setting mark's value to 100 and evaluating it as a Boolean (condition)

By convention, any numeric value that is not zero will return true when evaluated as a condition
