QUESTION 1

There are many of issues affecting cost of software. List and explain the five parts affecting pricing in software.

QUESTION 2

char *strncat (char *dest, const char *src, size_t count)
{
char *temp=dest;
if( count) {
while(*dest)
dest++;
while((*dest++ = *src++)){
if( --count == 0){
*dest = ‘\0';
break;
}
}
}return temp;
}

(a) Sketch a control flow graph for the above function.

(b) Figure out the Cyclomatic complexity based on your control flow graph.

(c) Using two other methods, show that the Cyclomatic complexity acquired in the above question is correct.

(d) List the set of independent trails from the graph.

QUESTION 3:

Think about the following scenario.
Suppose you work for a company that makes dwelling safety and security monitoring devices and controllers. Now your company desires to sell home safety systems. You are requested to plan and build the software part of the system. The obtainable components are:

• controller (with associated monitoring devices) for door and window alarms

• controller (with associated monitoring devices) for motion detectors

• controller (with associated monitoring devices) for panic buttons

• controller (with associated monitoring devices) for fire detector

• controller (with associated devices) for light activator and deactivator

• controller/monitor for key device (to turn system on and off)

• wireless dial-out device with controller

(a) Evidently state your assumption and calculate the Adjusted Function Point.

(b) Calculate approximately the effort (time taken) to build the system. Presume a productivity of 10FPs per staff month.

QUESTION 4

(a) Portray the types of metrics we have in software development.

(b) List four problems that project managers encounter before starting and during the course of expansion phase of a software project

QUESTION 5

void sort( int *a, int n )
{
int i, j, t;
if( n <2 ) return;
for( i=0 ; i {
for( j=i+1 ; j {
if( a[i] > a[j])
{
t=a[i];
a[i] =a[j];
a[j]=t;
}
}
}
}

Concerning Halstead's metrics, calculate the following:

(a) volume

(b) difficulty

(c) effort

Note: Ignore function definition

QUESTION 6

A lot of software companies still make use of subjective estimation techniques while replying to Request for Proposals (RFPs). List and illustrate four common estimation models.

QUESTION 7

char *strncat (char *dest, const char *src, size_t count)
{
char *temp=dest;
if( count) {
while(*dest)
dest++;
while((*dest++ = *src++)){
if( --count == 0){
*dest = ‘\0';
break;
}
}
} return temp;
}

(a) Conclude the Information Flow Complexity.

(b) Compute the Weighted IFC.
