Question

c/c++

This is a simple debugging question. The program (as written) tries to add up the elements of two arrays and store the results into a third array. The idea is that every element of the third array equals the sum of the two corresponding (i.e same index or position in the array) elements in the first two arrays. There is a syntax error, because the way it is written is not the correct way to do it. You are to fix that by replacing the wrong method with the right one. When this (and other possible errors) is done, the output should look like the one in the sample run. The name, ID and section number that appear at the beginning of the output of the program should be your own, not the ones used in the sample Sample run: My name: Smith, Peter My ID: 309999999 My section: 61 C[0] = 11 c[1] = 22 C[2] 33 C(3) 44 C[4] = 55 Press any key to continue .. */

Answer 1

I have included the entire program below

In your code you need to sum the elements using a for loop:

for(int i=0;i<5;i++)

c[i]=a[i]+b[i]; This will add the elements at the corresponding index.

Moreover array index starts at 0 so for printing the array you must use this loop for(int i=0;i<5;i++)

I have written a generic code which takes input from the user and adds the element.

You code needs the modifications as stated above

#include <iostream>

using namespace std;

int main() {

    int c;

    cout<<"\nEnter the number of columns of the array: "; //Enters the number of columns

    cin>>c;

    int a[c],b[c],sum[c]; //Declaring 3 arrays

    cout<<"\nEnter the elements of array 1: "; //Prompts to enter array 1

    for(int i=0;i<c;i++)

    cin>>a[i];

    cout<<"\nEnter the elements of array 2: "; //Prompts to enter array 2

    for(int i=0;i<c;i++)

    cin>>b[i];

    for(int i=0;i<c;i++)

    sum[i]=a[i]+b[i]; //Computes the sum of array

    cout<<"\nResultant array is: ";

    for(int i=0;i<c;i++) //Displays resultant array

    cout<<sum[i]<<" ";

}
