C control reaches end of non void function

With these it helps You declare get_proper_int to return a value of type int, but there's no return statement anywhere in the function.
Add it to the end of the function:
code :
int get_proper_int(string prompt) 
{  
    int n;
    do
    {
        n = get_int("%s",prompt);
    } while (n<1||n>8);  
    {
        for (int j = 0; j < n; j++)
        {
            printf("#\n");
        }
    }
    return n;
}

around this issue If your function can legitimately fail to find a matching Cluster, then you should have it return a pointer:
code :
Cluster* Myclass::getCluster(const Point &p)
{
    foreach (Cluster c, *this)
        foreach (Point point, c)
            if (point == p)
                return &c;
    return 0; // or return nullptr; in C++11
}
Cluster* Myclass::getCluster(const Point &p)
{
    foreach (Cluster& c, *this)
        foreach (Point point, c)
            if (point == p)
                return &c;
    return 0; // or "return nullptr;" in C++11
}

I hope this helps you . Your return type is void* if you dont want to return anything it should be void. The same could be said about the argument you're taking for your function.
void* foo(void*) // this takes a void* as paremeter and is expected to return one too

To fix the issue you can do Returning NULL is fine, and is the normal way. Nothing will use the return value unless you write code to use it. NULL is a valid value for void *, and if you don't care what that value is, then the only thing that matters is that it's a valid one.

I hope this helps . int triangleNumbersBelow(int n) { means the function has to return an int value, but you never did
in fact you do not have to return a value because the python version don't return a value, so change its signature by void triangleNumbersBelow(int n) {

This might help you For starters the function has undefined behavior because it uses an unitialized pointer.
And the function shall have a return statement if its return type is not void.
code :
#include <stdio.h>

void read_line( char *buf, size_t sz ) 
{
    while( fgets(buf, sz, stdin) && buf[0] != '\n' ) 
    {
        fputs(buf, stdout);
    }
}

int main( void ) 
{
    enum { N = 1024 };
    char buf[N];

    read_line( buf, N );
}
#include <stdio.h>

char * read_line( char *buf, size_t sz ) 
{
    if  ( fgets(buf, sz, stdin) && buf[0] != '\n' ) 
    {
        return buf;
    }
    else
    {
        return NULL;
    }
}

int main( void ) 
{
    enum { N = 1024 };
    char buf[N];

    char *p = read_line( buf, N );\

    if ( p != NULL ) fputs( p, stdout );
}
