[ad_1] You need to set isPrime to 0 each time the user enters a number. Otherwise, it still holds the value from the previous number. Move the variable declaration int isPrime = 0; inside the while loop. BTW, isn’t that variable name backwards? You set it to 1 (i.e. true) when you discover that there’s … Read more
[ad_1] Let’s see. Assume first time it runs, x,y is 1,1. So you add Box(1,1). Next time is run, let’s assume x,y is 2,3. So, enter for loop: i = 0: Not same x,y, so enter else, and add Box(2,3). i = 1: Same as x,y (yeah, we just added it), so enter if and … Read more

[ad_1] No, that is an absolutely pointless use of exit(). If you absolutely need one, just put it at the end of the script. Using exit() like that is only useful if you provide an exit code (used in command line applications). [ad_2] solved What is the point of exit() after each if statement? [closed]
[ad_1] Without knowing why you want to use a single if, it’s hard to tell. Of course, you can use ternary operators without any ifs: unsigned int x, y; cin>>x; y = x<=1 ? 1 : x<=3 ? 2 : x<=5 ? 3 : 6; Or ugly boolean casting hacks for exactly one if (please … Read more
[ad_1] So far, you have the right idea. I am going to assume based on your syntax, that you are using an array. Your get() method looks good, but you are missing some code from your remove() method. public int remove(int index){ //check for out-of-bounds if(index < 0 || index >= size) //assumes size is … Read more
[ad_1] It can be done – however your function should be returning an int. int foo(void) { return 1; } int main(void) { switch(foo()) { case 0: printf(“foo\n”); break; case 1: printf(“bar\n”); break; default: break; } return 0; } As, can been seen this compiles and runs.

[ad_1] if 0 in (result1, result2, result3): is equivalent to: if result1==0 or result2==0 or result3==0: What you want is this: if (0,0,0) == (result1, result2, result3): Which is equivalent to: if result1==0 and result2==0 and result3==0: You could actually even do this: if result1==result2==result3==0: since you’re checking to see if all 3 variables equal … Read more

[ad_1] To answer your first question. By doing an if statement in one line you are limited to one operation, so to speak. if(ret != 0) return false; Whilst using the curly brackets you are declaring a block with code operations. if(ret != 0) { /* do other stuff here */ return false; } There … Read more
[ad_1] if Enter == “Yes” or “yes”: This is not how or works. This is interpreted as if (Enter == “Yes”) or “yes”:. In python, non-empty strings are always true, so all of the if statements like that will be true. I would suggest something like if Enter.lower() == “yes”: which takes care of all … Read more
[ad_1] if v < e: v = e can be read: “If v is less than e, make v the value of e.” As above you should put a new line to make it read easier: if v < e: v = e [ad_2] solved Python : What is the purpose of a colon in … Read more
[ad_1] Have a think about how you can code simple mathematics into your program, I will start you off with an example. if (productCost >= 20 && productCost < 60) { discount = 0.9; } What this does is check if the cost of the product lies between 20 and 60 and if it does … Read more
[ad_1] You need to write these conditions, (11<=type_c<=15) as (11<=type_c && type_c<=15). [ad_2] solved Logical errors and incorrect output when testing if an integer is in a range [duplicate]
