• A game where the user has to try to form the longest dictionary word from a set of random letters (vowels and consonants).

This is the criteria:

The code that you use to produce that application must use a combination of at least two of:

Loops

Vectors or Arrays

Conditional execution

Optionally, your code might embed:

Functions.

Visualisation of data

Write a C++ program in which, read integers from file “data.txt” into an integer array. First element of integer arrayshows the number of records. After that number of recordthere is another integer which shows the other number of records.

Write a C++ program in which, read integers from file “data.txt” into an integer array. First element of integer array shows the number of records. After that number of record there is another integer which shows the other number of records.

Write C++ program, with multiple functions, that reads text, txt, from the file and accepts two patterns, pat and rpat, from the user. The program replace all occurrences of pat from the txt with rpat. The program output shall be as shown below in the example. without using string

1- Consider the following set of processes, with the length of the CPU-burst time given in

milliseconds:

Process burst Time Priority

P1 10 3

P2 1 1

P3 2 3

P4 1 4

P5 5 2

a. Draw a Gantt chart to show how these processes would be scheduled.

b. Give the turnaround time (total time from first arrival into ready state until CPU-burst

is completed) of each process.

c. Give the waiting time (total time spent in the Ready state) of each process.

d. Give the average waiting time of all the processes.

e. Create Program for SJF for above data.

2- Suppose the following three processes arrive for execution at the arrival times

indicated.

Process Arrival Time Burst Time

P1 0.0 8

P2 0.4 4

P3 1.0 1

a. Develop code for SJF scheduling using above given data.
