12-Consider the following skeletal C program that uses static scope and stack dynamic local variables; void funl (float r) { int s, t 1 fun2 (s); void fun2 (int x) { int y; ... fun3 (y), 2. 3.

C++ Please answer in 30 min please What are the prototype and definition of a new member function int size() to the class Stack based on compile array which returns the current size (number of actual items) in your object of type Stack.

Please help c++language

Data Structure Using C++  I need a function like this ::: float postfixEval(string postfix) {int a, b;stack<float> stk;string::iterator it;for(it=postfix.begin(); it!=postfix.end(); it++) {//read elements and perform postfix evaluationif(isOperator(*it) != -1) {a = stk.top();stk.pop();b = stk.top();stk.pop();stk.push(operation(a, b, *it));}else if(isOperand(*it) > 0) {stk.push(checkNumber(*it));}}return stk.top();} to evaluate postfix with more one digit in expression (multi digits) please just this function simple like the above

C programming fill in the following code  #include "graph.h" #include <stdio.h>#include <stdlib.h> /* initialise an empty graph *//* return pointer to initialised graph */Graph *init_graph(void){} /* release memory for graph */void free_graph(Graph *graph){} /* initialise a vertex *//* return pointer to initialised vertex */Vertex *init_vertex(int id){} /* release memory for initialised vertex */void free_vertex(Vertex *vertex){} /* initialise an edge. *//* return pointer to initialised edge. */Edge *init_edge(void){} /* release memory for initialised edge. */void free_edge(Edge *edge){} /* remove all edges from vertex with id from to vertex with id to from graph. */void remove_edge(Graph *graph, int from, int to){} /* remove all edges from vertex with specified id. */void remove_edges(Graph *graph, int id){} /* output all vertices and edges in graph. *//* each vertex in the graphs should be printed on a new line *//* each vertex should be printed in the following format:…

Consider the function definition:  void GetNums(int howMany, float& alpha, float& beta) {   int i;   beta = 0;   for (i = 0; i < howMany; i++) {     beta = alpha + beta;   } } Describe what happens in MEMORY when the GetNums function is called.
