错误:数组下标无效的类型'long double ** [long double]'

long double** make2darray(long int V)

{

    long double **array2,i;
    array2 = (long double**) malloc (V*sizeof(long double*));
    for(i=0;i<V;i++)
    {
        array2[i] = (long double*) malloc (V*sizeof(long double));
    }
return array2;

}

最佳答案

数组中的索引必须始终具有整数类型，您需要将声明更改为:

long double **array2;
size_t i;

1. One of the expressions shall have type ‘‘pointer to complete object type’’, the other expression shall have integer type, and the result has type ‘‘type’’.
