How do you write a program in c plus plus that reads two integer arrays each having 10 elements and then prints the sum of the products?

Answer 1

#include<iostream>

#include<iomanip>

#include<time.h>

void print(int a[], size_t size)

{

using std::cout;

using std::endl;

using std::setw;

for(size_t index=0; index<size; ++index)

cout<<setw(5)<<a[index];

cout<<endl;

}

int main()

{

srand((unsigned)time(NULL));

const size_t size=10;

int a[size], b[size], c[size];

// Initialise a and b with random integers (range 1-99)

for(size_t index=0; index<size; ++index)

{

a[index]=rand()%99+1;

b[index]=rand()%99+1;

}

// Initialise c with products of a and b.

for(size_t index=0; index<size; ++index)

c[index]=a[index]*b[index];

// Calculate sum of c.

int sum=0;

for(size_t index=0; index<size; ++index)

sum+=c[index];

// Print results.

std::cout<<"Array a:\t"; print(a,size);

std::cout<<"Array b:\t"; print(b,size);

std::cout<<"Products:\t"; print(c,size);

std::cout<<"Sum product:\t"<<sum<<std::endl;

}

Answer 2

#include<stdio.h>

int main (void) {

int array[10];

int i, sum = 0;

for (i=0; i<10; ++i) {

scanf ("%d", &array[i]);

sum+= array[i];

}

printf ("The sum of the array is: %d\n", sum);

return 0;

}

Answer 3

#include<stdio.h>

int main (void) {

const int max = 10;

int nums[max]; int sum;

sum = 0;

printf ("Enter 10 integers: ");

for (int i=0; i<max; ++i) { scanf ("%d", &nums[i]); sum += nums[i]; }

printf ("The sum of the integers is: %d\n", sum);

return 0;

}
