Question

2. Write a C program that using arrays A and B calculates the given formula. The program should save the results in the Carray and then print it. int A[7] = {215, 431, 25, 64, 18, 99, 105); int B[7] = {50, 78, 31, 477, 22, 258, 312); (100 Points) C[i] (A[i]+B[i])x2 median (A)+median(B) Enter your answer

Answer 1

#include<stdio.h> int main(){ //given int A[7] = { 215,431,25,64,18,99,105}; int B[7] = { 50,78,31,477,22,258,312}; int A_copy[7] , B_copy[7]; //copy elements of A in A_copy and elements of B in B_copy for (int k = 0; k < 7; ++k) { A_copy[k] = A[k]; B_copy[k] = B[k]; } //lets find median of array A and B // first we need to sort //using bubble sort to sort arrays int temp ; for (int i = 0; i < 7; ++i) { for (int j = 0; j < 7-i-1; ++j) { if( A_copy[j] > A_copy[j+1 ]){ //swap both elem temp = A_copy[j]; A_copy[j] = A_copy[j+1] ; A_copy[j+1] = temp ; } } } // similarly find B_sort for (int i = 0; i < 7; ++i) { for (int j = 0; j < 7-i-1; ++j) { if( B_copy[j] > B_copy[j+1 ]){ //swap both elem temp = B_copy[j]; B_copy[j] = B_copy[j+1] ; B_copy[j+1] = temp ; } } } int mid_a , mid_b; //median element will be the 4th element in the array mid_a= A_copy[3]; mid_b = B_copy[3]; double C[7]; for (int i = 0; i < 7; ++i) { C[i] = (double)((A[i] + B[i])*2)/(double)(mid_a + mid_b); } //print contents of array C printf("Contents of array C are as follows : \n"); for (int m = 0; m < 7; ++m) { printf("%f\t" , C[m]); } } 

Contents of array C are as follows: 2.994350 5.751412 0.632768 6.112994 Process finished with exit code o 0.451977 4.033898 4.711864
