C++ program to print the sum of prime numbers in an array.

Answer 1

Solution.

//Connectinglibrary
#include"stdafx.h"
#include<stdlib.h>
#include<iostream>

usingnamespace std;

//Functioncomputing the sum of prime numbers
intFuncSum(int* a,intsize)
{
intsum=0;
boolbState=true;
for(int i = 0; i < size; i++)
{
for(int j = 2; j <a; j++)
{
if(a[i]% j == 0)
{
bState=false;
break;
}

}
if(a[i]>1&& bState)
{
sum+=a[i];
}

}
returnsum;
}

//Themain function
intmain()
{
inta[]={2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 4, 6, 9};//array

cout<<"Amountof prime numbers in an array: "<<FuncSum( a,sizeof(a)/sizeof(a[0]))<<endl;

//system("pause");
return 0;
}
