Write a program in C/C++ to calculate the value of “ ” by using the series expansion given below:

cosx=1-x²/2! + x^⁴/4! - x⁶/6!+.........

Note:

 Evaluate only upto first three terms.

 Also find the value of by using the inbuilt function.

 Compare the results i.e., the result produced by your program and that produced by inbuilt function. Based on comparison, determine error.

LOOPS

Let diff = the absolute value of (num – guess). If diff is 0, then guess is correct. diff is not 0. Then the program outputs the message as follows:

1. If diff is greater than or equal to 50, the program outputs the message indicating that the guess is very high (if guess is greater than num) or very low (if guess is less than num).

2. If diff is greater than or equal to 30 and less than 50, the program outputs the message indicating that the guess is high (if guess is greater than num) or low (if guess is less than num).

3. If diff is greater than or equal to 15 and less than 30, the program outputs the message indicating that the guess is moderately high (if guess is greater than num) or moderately low (if guess is less than num).

4. If diff is greater than 0 and less than 15, the program outputs the message indicating that the guess is somewhat high (if guess is greater than num) or somewhat low (if guess is less than num).

Create a C++ program based on the requirements below:

After get a grade from the user, the program will determine what will be the corresponding grade equivalent.

Conversion Table

101 and higher - Out of Range

90 to 100 - Excellent

80 to 89 - Very Good

75 to 79 - Good

74 and below - Failed

Sample Output:

Enter Grade: 79

The equivalent of 79 is Good!
