Nettetint a = 7; int b = 3; double c = 0; c = a / b; c ends up having the value 2, rather than 2.3333, as one would expect. If a and b are doubles, the answer does turn to 2.333. But surely because c already is a double it should have worked with integers? So how come int/int=double doesn't work? c++ variables double integer-division Share Nettet11. nov. 2024 · 本篇 ShengYu 介紹 C/C++ static 的用法與範例，C/C++ 使用 static 通常有兩種目的，一種是限制變數的作用域(scope)，作用域的意思是變數在程式中可以被存取的範圍，另一種目的則是讓變數生命週期變得跟程式一樣長，C/C++ static 的概念與用法也容易出現在考試或面試的題目裡。
