两个连续素数之间的最大差异

Question

这是一个用C编写的简单程序，它向用户询问int n 找出从2到n范围内的两个连续素数之间的最大差异的最佳方法是什么？

int main() {
    int n, i, j, c;
    clrscr();
    printf("Enter Range To Print Prime Numbers:");
    scanf("%d", &n);
    printf("Prime Numbers Are Following:\n");
    for(i=1, c=0; i<=n; i++) {
        for (j=1; j<=i; j++)
            if (i % j == 0)
                c++;
        if (c == 2)
            printf("%d ", i);
    }

    printf("\n\n The highest difference between numbers is:");

    /* logic i cant get */
    getch();
}

Answer 1

跟踪变量中两个连续素数之间的最大差异，如果新差异较大，则用新差异替换变量。

int maxDifference = 0;
int currentDifference;

// begin looping
currentDifference = calculateNewDifference();

if(currentDifference > maxDifference) {
    maxDifference = currentDifference;
}
