请编写c语言程序完成下列问题：样例输入a150b65样例输出102111101提示 要求使用位运算完成上述转换操作

#include <stdio.h>

int main() {
    char s[] = "a150b65";
    int num = 0;
    int i = 0;
    while (s[i] != '\0') {
        if (s[i] >= '0' && s[i] <= '9') {
            num = num * 10 + s[i] - '0';
        } else {
            printf("%d.", num);
            num = 0;
        }
        i++;
    }
    printf("%d\n", num);
    int a = num / (1 << 24);
    int b = (num % (1 << 24)) / (1 << 16);
    int c = (num % (1 << 16)) / (1 << 8);
    int d = num % (1 << 8);
    printf("%d.%d.%d.%d\n", a, b, c, d);
    return 0;
}
