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

A container holds a collection of objects of a particular type.The standard library vector type is a sequential container. It aggregates a single type element called a container, and then stores and accesses the elements based on their location,

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
