If you know the unit prices of two different brands of an item you are better able to

write a 2d array c program that can capture marks of 15 students and display the maximum mark, the sum and average

bekas [8.4K]

Answer:

#include <stdio.h>

int MaxMark(int* arr, int size) {

int maxMark = 0;

if (size > 0) {

maxMark = arr[0];

}

for (int i = 0; i < size; i++) {

if (arr[i] > maxMark) {

maxMark = arr[i];

}

return maxMark;

}

int SumMarks(int* arr, int size) {

int sum = 0;

for (int i = 0; i < size; i++) {

sum += arr[i];

}

return sum;

}

float AvgMark(int* arr, int size) {

int sum = SumMarks(arr, size);

return (float)sum / size;

}

int main()

{

int student0[] = { 7, 5, 6, 9 };

int student1[] = { 3, 7, 7 };

int student2[] = { 2, 8, 6, 1, 6 };

int* marks[] = { student0, student1, student2 };

int nrMarks[] = { 4, 3, 5 };

int nrStudents = sizeof(marks) / sizeof(marks[0]);

for (int student = 0; student < nrStudents; student++) {

printf("Student %d: max=%d, sum=%d, avg=%.1f\n",

student,

MaxMark(marks[student], nrMarks[student]),

SumMarks(marks[student], nrMarks[student]),

AvgMark(marks[student], nrMarks[student]));

}

return 0;

}

Explanation:

Here is an example using a jagged array. Extend it to 15 students yourself. One weak spot is counting the number of marks, you have to keep it in sync with the array size. This is always a problem in C and would better be solved with a more dynamic data structure.

If you need the marks to be float, you can change the types.

What is probably the most revolutionary innovation since the printing press?

BARSIC [14]

Answer:

The Internet

Explanation:

Why? The internet has done twice if not thrice what the printing press has done. The printing press allowed for dissemination of information and knowledge to the population through its mechanical movable printing capability and speed of book publishing. However its reach was highly limited by the physical attributes of the machines and having to transfer books and papers in spreading them to certain destinations. This limitation has been eliminated by the internet as one is able to receive a book written today in seconds and not physically but through electronic means. In other words, information need not be transferred physically, also accessbility and cost of getting information has been highly improved with the internet.

Edith’s warehouse (adjusted basis of $450,000) is destroyed by a hurricane in October 2018. Edith, a calendar year taxpayer, rec

deff fn [24]

Answer:

Check the explanation

Explanation:

the step by step solution to the question is;

a. the answer to question A

The Realizable gain=insurance proceeds less adjusted basis = 525,000 - 450,000 = $ 75,000

The Realizable gain will be zero(0) due to the transaction being an involuntary conversion, Mr. E is eligible to section 1033 benefit that the gain of 75,000 is postponed.

The Basis of replacement property = cost of warehouse less postponed gain = 550,000 - 75,000 = $ 475,000

b.the answer to question B

The Realizable gain = insurance proceeds less adjusted basis = 525,000 - 450,000 = $ 75,000

The Realizable gain = divacancy in reinvestment less insurance proceeds less reinvestment = 525,000 - 500,000 = $ 25,000

The Basis of replacement property = cost of warehouse less postponed gain = 500,000 - 50,000 = $ 450,000

c.the answer to question C

The Realizable gain = insurance proceeds less adjusted basis = 525,000 - 450,000 = $ 75,000

The Recognized gain = 75,000
