这个怎么编啊？刚入门🙏🏻

Question

求s的值，x,y由用户从键盘输入。

s=(x+2)(y+3)+(x+22)(y+33)+(x+222)(y+333)+(x+2222)(y+3333)

…+(x+2^10)*(y+3^10)

Answer 1

供参考：

#include <stdio.h>
int main()
{
    int    x,y,i;
    double t2 = 0,t3 = 0;
    double s = 0;
    scanf("%d%d", &x, &y);
    for (i = 1;i <= 10;i++){
        t2 = t2*10 + 2;
        t3 = t3*10 + 3;
        s += (x+t2)*(y+t3);
    }
    printf("%f", s);
    return 0;
}
