C语言中如何计算两个集合之间的差异

计算两个集合之间的差异是在C语言中常见的问题。差异是指两个集合中不同元素的数量或内容的差异。在解决这个问题之前，我们首先要了解集合的定义和相关操作。

c
#include 
int calculateDifference(int set1[], int size1, int set2[], int size2) {
    int difference = 0;
    int i, j;
    int found;
    for(i = 0; i < size1; i++) {
        found = 0;
        for(j = 0; j < size2; j++) {
            if(set1[i] == set2[j]) {
                found = 1;
                break;
            }
        }
        if(!found) {
            difference++;
        }
    }
    return difference;
}
int main() {
    int set1[] = {1, 2, 3, 4, 5};
    int size1 = sizeof(set1) / sizeof(set1[0]);
    int set2[] = {4, 5, 6, 7, 8};
    int size2 = sizeof(set2) / sizeof(set2[0]);
    int difference = calculateDifference(set1, size1, set2, size2);
    printf("两个集合的差异为：%d\n", difference);
    return 0;
}
