我尝试使用一种稍微优化的算法来寻找素数#

来解决项目euler的第10个问题

#include<stdio.h>
#include<math.h>

long long int main() {
    int flag =1;
    long int lim = 199999; //upto which the prime is to be generated
    long int purposedPrime = 2;
    long int PrimeSet[200000] = {0}, count=0; 
    long int i;
    float sRoot_PP;
    long long int Sum = 0 ; //This is for prj_euler :)
    PrimeSet[count] = 2; count++; purposedPrime++;
    PrimeSet[count] = purposedPrime ; count++;
    Sum = 5 ;
    while(purposedPrime < lim){
        flag = 1;
        purposedPrime += 2;
        sRoot_PP = sqrt(purposedPrime);
        for(i=0; i<count; i++){
            if(PrimeSet[i]>sRoot_PP) break;
            if(purposedPrime % PrimeSet[i] == 0){ flag = 0; break;}
        }
        if(flag == 1){
            PrimeSet[count] = purposedPrime ;
            count++;
            Sum += purposedPrime;
        }
    }

    printf("Total Count: %d", count);

    printf("\n");
    printf("Sum : %ld", Sum);
    return Sum;
}

我在本地机器上运行它:Codeblocks with MinGW in Win8。输出

Total Count: 17984
Sum : 1709600813
Process returned 7096800813 (0x65E6702D) execution time : 0.063 s
Press any key to continue

我在codepad中运行了它。输出

Total Count: 17984
Sum : 1709600813
Exited: ExitFailure 45

在这两种情况下输出都不正确。我个人认为必须对显示的错误做些什么。指向的错误是什么?

1 个答案:

答案 0 :(得分:1)

错误指向您从主函数返回非零值。要解决该错误,只需将return Sum替换为return 0即可。但是,它对你的结果没有帮助。同样,我将main的返回值更改为int,但这实际上也没有任何区别。
