[ad_1] Your code divides by zero whenever a and b are 0. That’s not going to work. You need to change your loop to check the values before you try to use them. [ad_2] solved Why is this simple thing giving an error?

[ad_1] So, if I’m using a language with pointers and unsafe arrays, and crazy things start happening, then I have to soon suspect that I’m overwriting memory. There are many ways to do this: writing past the end of an array, using an uninitialized pointer, free()ing something that was never malloc()ed, etc. If that’s what’s … Read more

[ad_1] I’m not sure exactly what you were trying to do with your second loop in the pop function but this modified pop should display the popped value as well as the existing contents. void pop (tindanan *t) { int i; if(kosong(t) == 1) cout<<“\nTindanan Kosong\n”; else { cout<<“\nPop Item: ” << (t->senarai[t->atas]); t->atas–; cout<<“\nkandungan … Read more

[ad_1] I don’t know about such function, however you can simply create one: just add absolute values: #include <iostream> int sumAbs( int a, int b) { return std::abs( a) + std::abs( b); } int main() { int a = -5; int b = 10; std::cout << sumAbs( a, b); // 15 return 0; } [ad_2] … Read more

[ad_1] Why is cout << “geeks”; inside the if condition executed? Because otherwise the computer won’t know whether it was “true” or “false”? Given if (foo()), the function foo must be called; this extends to any expression in general, which must be evaluated before their “result” can be known (though note that sub-expressions may be … Read more

[ad_1] If DeliveryGoal is a string, then just declare it as a string literal: “88%” If it is a double, then parse the double and add the symbol: string percent = (val * 100).ToString() + “%”; Alternatively, you can have the ToString method format the double for you: string percent = val.ToString(“P”); See the MSDN … Read more
