Please Help Me Debug this Code

#include <iostream>
using namespace std;


int main()
{
double[100] r;
for (int i = 0; i < 100; i++)

for (int r = 0; r < 100; i++)
{
r(i) = rand() % 100;
}
return 0;
}

#include <iostream>
using namespace std;
 
 
int main()
{ 
    double[100] r;
    for (int i = 0; i < 100; i++)
 
    for (int r = 0; r < 100; i++)
    {    
    r(i) = rand() % 100;
    }
    return 0;
}

I'm pretty sure that won't compile. You have several errors:

double[100] r;
//should be
double r[100];
//
// the integer in the 2nd for loop is called "r" and so is the array; change one of them
//
r(i) = rand() % 100;   // use square brackets for indexing
//should be
r[i] = rand() % 100;
 

And a couple more things. You never seeded the random generator using srand() and you don't need two for loops.
