[問題] `main' must return 'int'
如題
我需要寫程式計算論文裡的數值(過大)
#include <stdio>
#include <math>
#include <iostream>
#include <cmath>
int c(int n, int k) {
if (k > n) {
return 0;
}
int r = 1;
for (int d = 1; d <= k; ++d) {
r *= n--;
r /= d;
}
return r;
}
void main()
{
int N=1088;
double Pe=10^-6;
int sum=0;
for (i=1;++;i<N)
{
sum+=c(N,i);
}
cout << sum;
return 0 ;
}
以上是程式碼 簡單來說c是combination
在compile時最後出現19 `main' must return `int'
P.S.1 使用的環境是DEV-C
2 我google過了 查到的是後面要return0
請問有高手能幫我解決嗎 先不管程式的正確性
