- • Write a program that will compute the students average • The user will input the following: Name Math Science English • If the average is equal and above 75, it will display “Congratulations. You passed the semester” otherwise “You failed the semester.” • However, if his average is equal and above 75 but fail to pass one or two subjects, it will display “Congratulations. You passed the semester. But you need to re-enroll (subject name) subject."Problem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }
- (Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?Problem: 2 (50 Points) Write a program that reads a set of integers, until the user will enter a negative number, then the program prints the sum of the even and odd integers.

- Exercise#1: Number Sequence Using nested loops, continue and break, write a program that prompts the user to input data for five students. Each student's data contains student first name and test scores. The program should accept positive integers only for test scores and ignore non-positive integers. Each student may has a different number of test scores; the program should receive input for test scores until input "0". Finally, the program outputs each student name with the sum of his/her marks. Sample Input/Output: Enter Student name: Khaled 65 78 -40 56 -25 89 0 The student 'Khaled' has the total marks = 288 Enter Student name: Kamal 37 55 44 -77 22 18 56 26 0 The student 'Kamal' has the total marks = 258 Enter Student name: Ali 66 33 87 66 87 -25 25 39 78 0 The student 'Ali' has the total marks = 481 Enter Student name: Taher 72 67 -33 0 The student 'Taher' has the total marks = 139 Enter Student name: Ahmed 75 68 84 -18 90 0 The student 'Ahmed' has the total marks = 317…V M Ol This code check whether a number is divisible by 5 and 11 or not. * 1... 2-. 3-... 4.. 1-lf ((n / 5 = 0) Not (n / 11 0)) Then 2-Print "divisible" 3-Else 4-Print "not divisible" 1-lf ((n Mod 5 = 0) And (n Mod 11 = 0)) Then 2-Print "not divisible" 3-Else 4-Print " divisible" 1-lf ((n / 5 = 0) 0r (n / 11 = 0)) Then 2-Print "divisible" 3-Else 4-Print "not divisible" 1-lf ((n Mod 5 = 0) And (n Mod 11 = 0)) Then 2-Print "divisible" 3-Elseif 4- Print "not divisible" 1-lf ((n Mod 5 = 0) And (n Mod 11 = 0)) Then 2-Print "divisible" 3-Else 4- Print "not divisible" 1-lf ((n / 5 = 0) And (n/ 11 0)) Then 2-Print "divisible" 3-Else 4-Print "not divisible"Part 2: One hour, Program writing a) Consider the following series, this series will evaluate the value of Y(x) from n = 0 up to infinity, for any value of x greater than 2.
