error initializer element not constant

static struct Queueptr * Header = (struct queueptr *) malloc (sizeof (struct queueptr));Wrong in compile times: initializer element is not constant Reason: Indicates that the initialization of global and static variables must be constant expressions

Look at the following code: #include int a = 1; int b = 2; int c = a+b; int main () { printf ("C is%d\n", c); return 0; } Gcc-o Test test.c Compile error: initializer element is not constant ----- Cause: The value of global variable

First:Use Func to declare a function, using the name and arguments to invoke the function. Use to specify the function return value.Use a tuple to return multiple values.The number of arguments to the function is variable, with an array to fetch

vector Container Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We refer to

Read again primer on the one hand is to check leaks, on the other hand is more in-depth understanding of the essence of C + + ideas. The details and understanding of each knowledge recorded in this review are recorded so as to facilitate subsequent

standard library vector type learning Vector Object Initialization method vector v1; Default constructor v1 is empty vector V2 (v1); V2 is a copy of V1, V2 and v1 must be of the same type, that is, when the type in angle brackets is
