Answer 1

你题目的解答代码如下：

#include<stdio.h>
int main()
{
    int x;
    char c;
    double s;
    scanf("%d", &x);
    s = (double)x;
    while (1)
    {
        scanf("%1s", &c);
        if (c==';')
            break;
        scanf("%d", &x);
        if (c=='*')
            s *= x;
        else if (c=='/')
            s /= x;
    }

    printf("%lf",s);
    return 0;
}
