Question

[C++, don't do more advance code than single-dimmension arrays and c-strings]

(Sum of Even random numbers) Write a program that generates twenty five random integers between 0 and 25 and displays the sum of even integers. (Hint: Use rand() % 25 to generate a random integer between 0 and 25. Use an array of 25 integers, say num, to store the random integers generated between 0 and 25.)

Answer 1

Program:

#include
#include
#include
using namespace std;
int main()
{
int num[25],sum=0; // variable declaration
int random_integer;
for(int i=0; i<25; i++){
num[i] = (rand()%25)+0; // Generate random numbers between 1 and 25
}
cout<<"Random numbers are:"< for(int i=0;i<25;i++)
{
cout< if(num[i]%2 == 0) // find even numbers
sum+=num[i]; // calculate sum
}
cout<<"\nSum of even imtegers is "< }

Output:

cc version 4.6.3 Random numbers are: 17 4 7 Sum of even imtegers is 120
