Function call problem
Hi, I'm new to programming and I need help with this problem. I have this piece of code:
1
2
3
4
5
6
7
8
9
10
11
12
13

#include <cstdlib>
#include <iostream>
using namespace std;
void add1(void)
{
double a[2]={3.1, 1.4};
double b[2]={3.5, 1.5};
double c[2];
c[0]=a[0]+b[0];
c[1]=a[1]+b[1];
printf("%1.1f %1.1f", c[0], c[1]);
}
int main(int argc, char *argv[])
{
add1();
getchar();
return 0;
}

I need to rewrite it this way, but it doesn't work:
1
2
3
4
5
6
7
8
9
10
11
12
13

printf("%1.1f %1.1f", c[0], c[1]);
}
int main(int argc, char *argv[])
{
add1({3.1, 1.4}, {3.5, 1.5}, {0.0,0.0});
getchar();
return 0;
}

double c[2]; // May want to initialize these to 0 or you'll get garbage.
add1(a, b, c);
getchar();
return 0;
