Consider the following policies for preventing deadlock in a system with mutually exclusive resources.

$$\,\,\,\,\,\,\,{\rm I}.$$ $$\,\,\,\,\,\,$$ Processes should acquire all their resources at the beginning of execution. If
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ any resource is not available, all resources acquired so far are released
$$\,\,\,\,\,{\rm II}.$$ $$\,\,\,\,\,\,$$ The resources are numbered uniquely, and processes are allowed to request
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ for resources only in increasing resource numbers
$$\,\,\,{\rm III}.$$ $$\,\,\,\,\,\,$$ The resources are numbered uniquely, and processes are allowed to request
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ for resources only in decreasing resource numbers
$$\,\,\,{\rm IV}.$$ $$\,\,\,\,\,\,$$ The resources are numbered uniquely. A process is allowed to request only
$$\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,$$ for a resource with resource number larger than its currently held resources

Which of the above policies can be used for preventing deadlock?

For the processes listed in the following table, which of the following scheduling schemes will give the lowest average turnaround time?

B	1	6
D	4	4
E	6	2

Consider the following C program segment.

#include < stdio.h >
int main()
{
    char s1[7] = "1234", *p;
    p = s1 + 2;
   *p = ‘0’;
    printf("%s", s1);
}

What will be printed by the program?

Consider a software project with the following information domain characteristics for calculation of function point metric.

Number of external inputs $$\left( {\rm I} \right) = 30$$
Number of external outputs $$\left( O \right) = 60$$
Number of external inquiries $$\left( E \right) = 23$$
Number of files $$(F) = 08$$
Number of external interfaces $$(N) = 02$$

It is given that the complexity weighting factors for $$I, O, E, F$$ and $$N$$ are $$4, 5, 4, 10$$ and $$7,$$ respectively. It is also given that, out of fourteen value adjustment factors that influence the development effort, four factors are not applicable, each of the other four factors have value $$3,$$ and each of the remaining factors have value $$4.$ The computed value of function point metric is _____________.
