这是我的代码

int main()?
{
    float avg, age[] = { 23.4, 55, 22.6, 3, 40.5, 18 };
    avg = average(age); /* Only name of array is passed as argument. */
    printf("Average age=%.2f", avg);
    return 0;
}

编译错误int main():

error: stray '\342' in program
error: stray '\200' in program
error: stray '\213' in program

我试图创建一个非常简单的程序来计算C++中两个对象之间的引力,所以我想为G声明一个宏,其值等于6.754*10 ^ -11,我用它 -

#define G 6.754e-11.0;

但是它产生了很多杂散错误,如下所示 -

aalpanigrahi@aalpanigrahi:~/Desktop/CS/C++/Other PSETS$ g++ gravity.cpp -o gravity
gravity.cpp:5:28: error: stray ‘\342’ in program
 #define G (6.754)*pow(10.0,??11.0);

     float gforce(float m1,float m2,float r){return G*m1*m2/(r*r);}
                                                    ^

我写了以下代码.它是实现双链表.但错误突然出现.

while(x==1); // This line showed errors
return 1;     

错误:

每当我与负数GCC进行比较时,我都会看到:

error: stray '\342' in program
   if ( -4 < ÔÇô3 ) return 1;
   ^
compilation terminated due to -Wfatal-errors.

码:

int main() {
  if ( -4 < –3 ) return 1;
  return 0;
}
