Thank you.A for construct is used to build a loop that processes a list of elements in programming. To do this, it continues to operate forever as long as there are objects to process. Is this assertion truthful or false? Explain your response.
- Array_based circular queue: Define the class Queue using one dimensional circular array representation with no implementation; i.e. declare the data members, and the function members only (Enqueue, Dequeue, IsEmpty, GetHead etc.). Implement the Ennqueue method of the above classFor any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }• Do not add statements that call print, input , or open , or add an import statement. • Do not use any break or continue statements.
