4 回答哪里錯(cuò)了#include <stdio.h> int main() { double num = 2.5; //定義浮點(diǎn)型變量num并賦值為2.5 int Num = (int) num; printf("num的整數(shù)部分是%d\n", num); return 0; }

4 回答#include <stdio.h> int main() { double num = 2.5; //定義浮點(diǎn)型變量num并賦值為2.5 printf("num的整數(shù)部分是%d\n", num); return 0; }

2 回答#include <stdio.h> int main() { double num = 2.5; //定義浮點(diǎn)型變量num1并賦值為2.5 printf("num的整數(shù)部分是%d\n", (int)num); return 0; }

2 回答#include <stdio.h> int main() { double num = 2.5; //定義浮點(diǎn)型變量num并賦值為2.5 printf("num的整數(shù)部分是%d\n",(int)(num)); return 0; }為什么整數(shù)部分是0

7 回答為啥可以運(yùn)行，但輸出錯(cuò)誤。#include <stdio.h> int main() { double num = 2.5; //定義浮點(diǎn)型變量num并賦值為2.5 int (num1) = (int)num; printf("%d\n", num1); return 0; }
