#include<stdio.h>
main()
{char c;
 
 float Mass, G,radian,n,m;   /*G unbalance grade.*/
 {

  do
   {printf("Please input the value of rotor mass\n");
    scanf("%f",&Mass);
    printf("Please input the value of the radius of the rotor\n");
    scanf("%f",&radian);
    printf("Please input the value of the G\n");
    scanf("%f",&G);
    printf("Please input the value of the service speed\n");
    scanf("%f",&n);
    m=(9549*Mass*G)/(radian*n);
    printf("The result is %f\n\n\n",m);
    system("pause");

    }
    while((c=getchar())!='\033');
}
}

按Esc键后出现"\"，但是无法退出程序。
如果把 while((c=getchar())!='\033');换成 while((c=getchar())!='\046');
按&键就能退出程序。
请各位指点啊！！

最后多了一个 }

删掉｝ 也不行啊

#include<stdio.h>
main()
{int c;

float Mass, G,radian,n,m;   /*G unbalance grade.*/
{

  do
   {printf("Please input the value of rotor mass\n");
    scanf("%f",&Mass);
    printf("Please input the value of the radius of the rotor\n");
    scanf("%f",&radian);
    printf("Please input the value of the G\n");
    scanf("%f",&G);
    printf("Please input the value of the service speed\n");
    scanf("%f",&n);
    m=(9549*Mass*G)/(radian*n);
    printf("The result is %f\n",m);
    getchar();
    }
    while((c=getch())!=27);
}
}
     getcher函数不能输入ESC

果然可以啊 ！！十分感谢啊！
