I need a solution to these c++ problems

Problem 1 (10) Air pressure is a function of altitude h. For each of the following location compute the air pressure p given that the relationship is:
p = 14.7*exp( - 0.000038*h )
Write a program to calculate air pressure p. The program should include:
*
A prompt for inputting data.
*
The printing of input and output data
Problem 2 (10) Write a program to calculate the interest(p) by using formula: p = 100*(1 + 0.05*n), where n - number of years. If n>5 a program calculates the interest by using formula:
p = 100*(1 + 0.05*(5 + 0.02(n - 5))).
Write a program using if - else statement. The program should include:
*
A prompt for inputting data.
*
The printing of input and output data
Problem 3 (20) Write a program that will generate every third integer, beginning with 2 and continuing for all integers that are less than 100. Calculate the sum of those integers that are divisible by 7. Write 3 program:
1.
using while statement,
2.
using do-while statement,
3.
using for statement.
Print the sum on the screen.
Problem 4 (20) An eraser falling out of a window is timed in its fall. Compute the height in feet and in meters from which the eraser fell. The relationship between free-fall distance d in feet and time t in seconds is: d = 16*t2 ( Hint: 1foot = 0.3048 meter). Write a program with a function that calculates distance d. The program should include:
*
A prompt for inputting data.
*
The printing of input and output data
Problem 5 (25) Write a program with a function that searches an integer one-dimensional array List for a value Item and returns its place in the array. If Item is not in the array List, represent the appropriate message. Add to program the function to initialize array and the function to print array. The program should include:
*
A prompt for inputting data.
*
The printing of input and output data
Problem 6 (15) Write a file-oriented program that will process the exam scores given in table:
