Question

im trying to fix this while loop but keep running into errors. Basically lets pretend I have 4 turtles, for every turtle that I sell I get a coin. Once I get to 0 I want to print how many coins I have. The error im getting is this,

error parentheses around assignment
used as truth value make: *** [cents]
Error 1

Here is the code:

while (turtles > 0) {
turtles = turtles - 1;
coin++;
if (turtles = 0)
printf("Now you have %d coins\n", coin);
}

Answer 1

Be glad that your compiler gave you that error.

You are assigning 0 to turtles in your if condition:

if (turtles = 0)

I suppose you are trying to test if it is equal to 0. Then it should be two equals == for equality instead.

if (turtles == 0)
