i want to solution for all this 7 Questions:

Question 1:
Implement a C++ program that multiples two numbers using pointers. 
For testing, do the following:
Enter the first integer: 8 
Enter the second integer: 11
Expected output: 
The multiplication of the two integers is: 88
Question 2:
Implement a C++ program that uses call by reference (in pointers) to multiply two 
numbers. 
For testing, do the following:
Enter the first integer: 8 
Enter the second integer: 11
Expected output: 
The multiplication of the two integers is: 88
Question 3:
Implement a C++ program that uses call by reference to calculate the factorial of a 
given integer using pointers. 
For testing, do the following:
Enter an integer: 4 
Expected output: 
The Factorial of 4 is: 24
Question 4:
Implement a C++ program that uses pointers to calculate sum of all elements in an 
array of integers. 
For testing, do the following:
Enter the element # 1: 2 
Enter the element # 2: 3 
Enter the element # 3: 6 
Enter the element # 4: 1 
Enter the element # 5: 7 
Expected output: 
The sum of the array is: 19
Question 5:
Use structure data type to enter the marks of 5 students in Programming, 
Algorithms, and Math courses (each course grade is out of 100). Then calculate 
and print the percentage of each student. 
That is, build a structure name StudentRecord that has five elements as follows: 
• Number
• Name
• Programming_marks
• Algorithms_marks
• Math_marks 
Then define an array of this structure, enter the data, and calculate and print the 
required. 
Question 6:
Write a C++ program that contains a structure specification that includes four 
variables: student name (less than 20 characters), homework grades (an array of 
four elements; each is out of 100), test grades (an array of three elements; each is 
out of 100), final average (the weighted average of the homework grades and test 
grades). Call this structure Student.
• Declare an array of three elements named studentlist from Student. 
• Enter name, homework marks, test marks, and then calculate the weighted 
average for each tuple. 
Question 7:
Write a C++ program that contains a structure, named student, that includes three 
variables: name (less than 30 characters), roll number (integer type), and date of 
birth (structure type; i.e., use nested structure). 
• Declare a variable named s from student. 
• Enter the s’s name, roll number, and date of birth. 
• Dispaly the s’s name, roll number, and date of birth
