#include<stdio.h>
#include<string.h>
int main()
{
    int k,n,a;
    char str[300];
    scanf("%d %d",&k,&n);
    while(n--)
    {
        scanf("%s",str);
        scanf("%d",a);
        if(strcmp(str,"multiply")==0)
            k=k*a;
        else if(strcmp(str,"minus")==0)
        k=k-a;
        else if(strcmp(str,"plus")==0)
            k=k+a;
    }
    printf("%d\n",k);
    return 0;
}
为什么这个程序运行不了。谁能给看看。谢谢！
