Question

C语言编程求两集合的差集，急急急！！！

不用指针，不用链表

Answer 1

#include <stdio.h>

int main(){
int a[10] = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19};//集合A
int b[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};//集合B

//打印A
printf("A: ");
int i;
for(i=0; i<10; i++){
printf("%d ", a[i]);
}
printf("\n");

//打印B
printf("B: ");
for(i=0; i<10; i++){
printf("%d ", b[i]);
}
printf("\n");

//打印A\B
printf("A\\B: ");
int j;
for(i=0; i<10; i++){
for(j=0; j<10; j++){
if(a[i] == b[j])
break;
}
if(j == 10)
printf("%d ", a[i]);
}
}
