Unexpected Output and Warning

Question

I am just playing around with what I have learned so far, up to the naming convention of variables. So I don't understand what I am doing wrong with the if/else. It doesn't seem to evaluate what I have in prens, plus I get this warning message in Code:Blocks:

warning: using the result of an assignment as a condition without parentheses [-Wparentheses]|

#include <iostream>

using namespace std;

int main()
{
string PlantName; //Pascal naming convention
bool plantState; //Camel naming convention

cout << "\n";
cout << "Please enter the plant name: ";
cin >> PlantName;
cout << "\n";
cout << "Is " << PlantName << " yellow and limp? [1=Yes:0=No]: ";
cin >> plantState;

if (plantState=1) {
cout << "\n";
cout << "Give " << PlantName << " some water." << endl;
cout << "\n";
} else {
cout << "\n";
cout << "Water " << PlantName << " every 2 days." << endl;
}
return 0;
}

Answer 1

= is assignment operator. Use == to compare.

if(plantState == 1){
// ...
}

Answer 2

Oi! Thank you, Shamima! How could I miss that!
