1、for循环

for (int i=1; i<=10; i++) {//奇偶数的输出
        if (i%2==0) {
            printf("i=%d\n",i);
        }else {
            continue;
        }
    }

2、while循环 和 do while循环

    int sum=0;
    int i=11;
    while (i<=10) {//while循环求和
        sum+=i;
        i++;
    }
    printf("sum=%d\n",sum);

    int sum=0;
    int i=11;
    do {
        sum+=i;
        i++;

    } while (i<=10);
    printf("sum=%d\n",sum);
