Question

Draw a flowchart to enter twenty integer data in a single dimensional array and to

Calculate the total sum of the array. Print the array and the sum in the output. ​

Answer 1

Algorithm:

1) Start

2) Declare an array of size 20, A[20]

3) Take input in the array from the user.

for(int i = 0 ; i < 20 ; i++)

    cin>>(A[i])

4) Declare a variable sum = 0

5) Start a loop to find sum

for(int i = 0 ; i < 20 ; i++)

    sum = sum + A[i]

6) Print all the elements

for(int i = 0 ; i < 20 ; i++)

    cout<<A[i]

7) Print sum

cout<<sum

8) End

Program in C++

#include<iostream>

using namespace std;

int main()

{

int A[20] , sum = 0;

cout<<"Enter elements : "<<endl;

for(int i = 0 ; i < 20 ; i++)

{

 cin>>A[i];

}

for(int i = 0 ; i < 20 ; i++)

{

 sum = sum + A[i];

}

cout<<"Elements are : "<<endl;

for(int i = 0 ; i < 20 ; i++)

{

 cout<<A[i]<<" "<<endl;

}

cout<<"Sum = "<<sum;

return 0;

}
